To do an AFH (the forwards version of an ABH), you need to be pressing S when you land/jump. The problem is, holding down S in the air massively slows you down, so to gain/preserve speed you need to tap S just when you land.

Using a controller, you can basically tape down the stick a bit so you're always inputting a tiny backwards movement. This is enough to trigger AFH, but doesn't slow you down much at all in the air. It takes a lot of skill out of the run (and also gives a blatant hardware advantage), which is why it was banned.

If you right click on livesplit and select 'edit splits' there are two tabs, one for real time and one for game time. If the autosplitter is working correctly it should automatically pause your timer during load times, which is how you get game time.

You can also change what your run is comparing against by right clicking and selecting 'compare against -> game time', which you should always use pretty much

For future reference - the above was discussed but in the end it was dropped, they only give a very slight advantage and it would be pretty tricky to moderate.

More people will help if you ask in the discord (https://discord.gg/Tvk9zP3), though you'll probably need to go into more detail about what specifically you're struggling with.

Compare to personal best is your best overall run. Compare to best segments is your best for each split (comparing against your gold splits)

Make sure your livesplit is set to compare against game time

Right click -> Compare against -> Game time

Just gonna add that what Dustin said is generally correct, but there are also some double edge glitches that aren't allowed, and they don't require saveloads. If it isn't listed as banned in the rules, its most likely allowed.

If you can't go through the glass, either you shot the wrong portal or you didn't preserve save glitch correctly. You might have gone too close to a portal before entering the elevator, or your shot under the elevator didn't land, or something like that.

Regardless, I'd agree with what Dustin said. 16/17 turret preserve is one of the hardest strats in inbounds. You can learn it if you want, but normally I'd recommend learning it last.
