Blackjack side count: has anyone actually tracked this successfully online

So I’ve tried adding a side count for aces and fives during online sessions, especially live dealer stuff, but I always seem to get tripped up by the shuffles and the pace. Theoretically it should help, but real-world conditions are just messy online and I always worry I’ve lost track after a few rounds. Does anyone have a routine or system to actually pull it off and make it worth the effort? Or is it basically just wishful thinking unless you’re playing super slowly?
