what @builderofcastles already said, calculating the value of a flag can be nontrivial. Depending on what interface does it in what way, you get an over or under approximation. Some just flat out say 0. But the pending payout should change.
I checked it. 7 days. Don't flag stuff that is already after 6.5 days or you will gradually get less out of your flag. If you flag after 7 days it should cost no vp but also have no effect.
Ok, that makes good sense, thanks.
I forgot to check the time.
Why isn't my delegation to @lucylin showing in his wallet?
I just checked and it isn't there.
