Yes I think it's the same 15 minute window - not sure what happen when Steem changes to 1 minute for the next fork.
Your Steem VP was in the 70's when I sent the link above earlier, but your Sports VP was almost at 100. With 2 accounts, it would be possible to balance these better.
Thx mate - so there s a tool to check your VP per Tribe, this is helpful and was one of the things I was searching for!
