My game completion rate is only 95%?

It says in my profile that my game completion rate is only 95%.

This can't be true since I always make sure to resign before leaving a game. Also, I checked the situation about a month ago and then the number was still 100%.

Furthermore, if we look at my losses (en.lichess.org/@/Blunders/loss), I can't find any instances of where I had left a game without resigning. Even if there existed couple of such instances, they wouldn't add up to 5% because I've played over 2000 games.

So, what is the logical explanation to this?

In some cases when you run out of time the computer count it like a possible quit, so I think it's because of this game that you didn't complete 100% of your games: fr.lichess.org/HZcc2vO2
The completion rate only apply for the last 10 or 12 games, so it's normal that for only one "suspicious" game, you completion rate fall to 95%

Yes I have 95% too, but regularly time out in blitz after playing too slow.

I also have 95%. Maybe it's because of some disconnections...I often use public wifi connections which are not very stable.

I'd assumed the reason is disconnections ??
But maybe you're lucky enough not to get those?

i also have a 95% completion rate, even though i have never disconnected.

i downloaded all my games, and TIME FORFEIT is listed in four of my games, each one a win for me. i think it would be nice to understand this issue, as it appears there may be a bug somewhere in this logic.
