For one thing, framing your accuracy in percentage instead of the obscure "centipawn loss" makes understanding how well you played much easier. BTW I've compared their analysis on a number of games, and it seemed like lichess is much tougher on you in what it defines as a blunder.

I disagree, ACPL is a well defined system, while nobody really knows what the accuracy means or how it's defined.

1 CPL, in short, is the loss of 1/100th of a pawn. Take the average of that and you get ACPL. So a ACPL of 100 means that you on average lost one pawn on every move (of course this isn't literal) that you played.

I've read the meaning and I can tell what the numbers mean, but it's still less intuitive than percentage.

Interesting, I find the exact opposite. Measuring things in terms of pawns give me a feel of how far behind I was from optimal play, whereas with the percentage, it's quite abstract. What does 70% accuracy mean?

[dvirsky]

That you're 30% far from optimal play :)

[shukantpal]

Yeah but what does “far” mean. You have experience with loss of pawns but not distance to optimal play

100% is only best moves (my record is 99.8%), anything above 90 is awesome, etc. I'm not sure what 15 ACPL means, but if you tell me 95% perfect it's more intuitive to me personally. But it might be because I'm not a very good and sophisticated player...
