Kradie filled me in on what angus said so I'll just leave this here.
I showed Deadcode exactly how I play BnG and he wrote this in the Discord channel:

The funny thing is, counting sprites is the only thing I've never bothered to do in BnG because my methods were always more accurate and useful anyway. But I do pay attention to the sprite and how the worm looks.
I measure my BnG based on full screen lengths because I play with 1152x864 resolution and always try to start off with a 3s grenade aimed at a full length screen because the worm and cursor has a distinct(to me) visual look so it's easy to tell if it's right. To get to that position I always move my cursor right to where it should go and have a really good eye for telling if that's correct.
Every shot I do, is based on that full screen distance, if the worm is closer or further than a full screen the aim is a little bit less or little bit more. I've put about 15k+ hours into BnG alone and because this game is based on incremental movements that all "slot" into place like a cogwheel it's pretty easy to tell your aim instinctually. If I miss, then it's usually only off by 1 or 2 notches at the most. So even if you aren't a counter in BnG like barman, Mablak, anubis, stylez, Darkz etc, it's not rocket science to realize your aim is off by the smallest amount you can move the crosshair.
Notch - The smallest movement possible.
Notching - Moving the cursor notch by notch.
Counting - Knowing that it takes X amount of notches to hit a worm based on the difference in distance between you and that worm and then "notching" to that position. THIS is the style that most players hate and are against.
Everybody notches and everybody is a notcher, but there are very few players who are counters.
But when someone says "They are a notcher!" they usually mean they are a counter. Counters are the players people usually hate playing against not people who naturally move in notches because it's impossible not to that's just how the game works.
The most important thing is knowing what type of shot to use, and being able to re-adjust if you miss.
The most controversial thing I ever did in BnG was apparently putting my thumb on the screen to re-aim.
I can say with pride that I've never cheated in BnG and grateful enough that a developer was there to defend me.
@angus It's nice to see your true colours though, one less person to give a fk about.
