Hello. I just payed attention that there is a wrong summing of edit sizes.
As you can see, 859+1700 = 0. I'm not sure, but maybe it has to do with all the edits made by bot.
- Open the Watchlist in group mode (I used this link.)
- (Possibly) Find a group with a couple bot only edits.
- Calculate the sum of them.
- Expected: the group sum will be the same.
- Got: the group sum is zero.
The relevant page has no more edits at that date.
If the bots are just a coincidence, I don't know what can be the cause. Thank you.
