Aim - The best way to improve your aim, is to go on 128 HS only servers (preferably around 30 - 50 ping). Do not spray, do not pre-fire everything. Aim first > then one tap shoot.
Spraying - Go on an empty server (Create your own), get yourself an AK / M4 (Try to practice with both, at least 5 - 10 minutes with each) and spray at the wall.

30 minutes every day and you should see an improvement in no time.
NOTE : This might not be the best way, but it has worked for me.
First half is bad advice. You don't want to go on 128 tick unless you will be playing on 128 tick (ESEA, CEVO, AltPUG), they feel and perform drastically different, so practicing on seperate tick rates compared to what you are playing on is a bad idea.
All the leagues and tournaments are held on 128 tick servers, not to mention 128 tick servers out perform the 64 tick potato servers on MM. Even though it's true that 64 tick servers are different to 128 tick servers, you're better off getting used to 128 tick.
No you aren't.... you're talking about silver 2's.... not global elites, they aren't going to any tourneys. I've played lots on both tick rates, there is a big difference and practicing on them is not recommended if you aren't playing on a PUG or league. Ask any pro, they will say the same. Hiko tells it religiously on his stream.
You do realize we are talking about aim here, right? Not spraying and praying, there is a reason why I added aim in front of it. It will still improve their aim.
P.S : They don't even need to shoot at the person, just put their crosshair on their head and manage to follow it, without flinching all over the place.
I don't think you even understand what difference tick rate makes. Playing on 128 tick as compared to 64 tick is near to the difference between LAN and online. There is a reason teams do better at LAN compared to online and vice versa, it is what they are used to, what they have their aim, movement, timings, sprays, etc. adjusted for, it's a very different environment and if you can't grasp that you aren't in the position to be giving tips on what servers to be using.
Ledger is right, he has a lot of experience and plays at a high eagle level even though that does not matter but since most people are "ohh rank is ur skill level" i will use it as a representation of his skill. When I started playing csgo and wanted to improve I went on 128tick servers and it worked, now I am Eagle Master and rocking those headshots. If you get good at 128tick, you will be good on 64 tick you will still get headshots, improve your spray etc. etc.
Source: Been playing csgo for several hundred hours, played against and with pros.
Right..... that's more experience than Hiko..... Steel.... several others..... hell I've been playing games like this since Raven Shield and I played 1.6 for years. Just because it worked for you doesn't mean it was more efficient, it's the simple fact of the matter. It's a different environment that has different timings and conditions to adapt to. Simple as that.

So fake I can't even handle it.
Don't be so sure, author is Richard Lewis and Shahzam did confirm it. Whether Shahzam is just being a scumbag is a different question (wouldn't be the first time), but it is very plausible. The way the ESEA ladder works, it wouldn't hurt IBP all that much.
Don't know why you brought other games in this, since we are talking about CS:GO not 1.6 or raven shield. And also don't know why you are talking about Hiko and Steel since no-where I mentioned I got experience of a pro, I would say I have a bit more experience than average cs:go player so that my advice would be somewhat valued. About the 128 tick dm servers, it worked for me, for my teammates, other friends and any other person I know that is highly ranked in matchmaking. As much as it is different on 128 tick servers and 64 tick it is no-where near to "oh the shots you get in 128 tick will mostly not happen in 64 tick" essentially you will still aim at a head and shoot which will most likely result in a headshot if you have the crosshair on the head perfectly and you can get the timing right which is not that much different on both of the servers.
Now please, ledger is trying to help people while you call his advice bad even though some people (like me) have benefited from this greatly and achieved a high rank in matchmaking which is what essentially most people are aiming for.

That's not how tick rate works. Tick rate is how many times a server refreshes in a given time, basically meaning it is the time to preform "so and so action" or an object to get to "from point a to point b". The effects and timing of this are very demonstrable by simply playing on a CS:S server (Accuracy values are the same for both AK's in CS:GO and CS:S) which runs at below 64 tick, standing idle, and shooting at a bot set to move in a strafing pattern. Chances are you will find yourself missing a lot more than hitting at perfect center mass of the head, and in order to account for it you will have to aim a very, very slight bit off to either side that the bot is moving towards, despite CS being about as close as you get to a game with hitscan, due to bullet travel time being nearly non existent, at least not to the extent you will have to account for it. Compare that to CS:GO and you will find even on 64 tick some accounting will need to be done, it's about a 1-2/10 chance that you will miss center mass head on a moving target (with perfect accuracy, same as the C:SS example), and worse aiming at the far side of a moving target, simply because the tick rate is not refreshing consistently as another tick rate you will be used to. The only way to make it more consistent is to account for it, which is where muscle memory kicks in. Tick rate is not a value of accuracy or probability, tick rate is a value of timing, meaning you can account for it. Obviously any server will teach you how to point your crosshair at things, but if you're accounting for any movement your muscle memory will be fucked on 64 tick rate if you've been accounting for 128. I guarantee you if you were to do an experiment with Dust 2 as the control, 64 tick practice for 3 hours, play 5 matches 64 tick, then 128 tick practice 3 hours, play 5 matches 64 tick, I guarantee you will find your accuracy on the first bout to better, if only slightly. But add that practice time on top of itself and it will quickly stack up and limit your consistency in accuracy.
And if you can't understand the premise of presenting the account of someone experienced in the subject of debate.... just stop. If you bothered to read my post properly at all you would see I was saying this is all advice that has been mentioned by pro players on stream when asked. They said it's like anything, when you play in a different environment with different conditions of which to adjust your muscle memory and reactions consistently throughout. Practice on servers where you will get both peeking and accuracy practice (Aim Maps, pistol maps, duel maps) and not on maps where you will find yourself running out in the open more than peeking corners (DM maps, casual modes, community TDM modes), practice in the same environment (Same tick rate, relatively same ping, practice online for online, and LAN for LAN if possible, use the same posture, same gear, same mouse positioning and style) so on and so forth. It's really common knowledge. You wanna play on a 128 tick PUG, then by all means practice on 128 tick servers, you will need to play on a PUG eventually at DMG + ranks anyways, if you want any kind of differentiation between the ranks.
Finally if you would bother to read my post I never said all his advice was bad, just that THIS particular advice was. Of course you will get better with good advice, I'm sure you learned movement tips, map tips, nades, strategies etc., I never claimed you didn't. I claimed his advice on practicing 128 tick was poor, claiming I said anything else is running away from the fact. If you want to use the fact he taught you to play better as your argument I could just say I self taught myself using this advice from watching Hiko and Shroud's streams and have achieved a similarly high rank, and then we will have come full circle. That's the simple fact of the matter.
