I just found a #MastodonBug, which is also a bug in #Fedilab @apps (FYI): with Fedilab polls rarely sum up to 100%, and then nearly ever the same as Mastodon. This is most likely a rounding error that both do without compensating, so it's more or less a display error, but it is a bug nonetheless. Here is an example for a poll where both fail to correct the wrong sum: https://tooot.im/@EhudNagar/109513566540079507
