Why do the webpage and the app show different stats?

Hi! can anybody explain why do the webpage and the app show different stats? I mean for example average opponent ranking (3 months). thanks

It seems likely one is wrong.

The app says my average opponent was rated 1428 in the last three months. It also says the average when I won was 1445, when I lost was 1477 and when I drew was 1447.

It makes no sense that the average of all opponents was lower than any of the the win/lose/draw averages.

Meanwhile, the webpage shows a 1457 average, which makes sense in the 1446/1477/1448 w/l/d averages.

looking at my own stats, I am going to guess that the app is wrong.

The average of 2, 6, and 7 is 5.

5 is lower than 6 and 7.

I don't understand what you mean.

Yes it is 5. That makes sense.

If you told me the average was 1, lower than any of the components, that wouldn't make sense.

1428 cannot be the average if component averages are 1445, 1477 and 1447.

Oh, I see.

but maybe before the last 3 months opponents were higher rated so no idea which one is correct
