I understand his scenario is 1 week but if you take the math out two weeks you lost money by doing it because the delegated SP will not be useable by either account for that second week, but using one account you would still get your 10 votes a day @ 100%.

Why do you think you can't use the SP for the second week? Here's the timeline: Day 1 vote with account a, delegate to account b, vote with account b, remove delegation.
Days 2-7 wait.
Day 8 vote with account a, delegate to account b, vote with account b, remove delegation.
Days 8-14 wait

Repeat ad infinitum.

Ok, double voting with the same Steem Power is possible, but it is also profitable? Keep in mind that both accounts now are not able to vote the next 7 days with the delegated SP. Meantime other accounts can vote 10 times with 100% per day.

Because it is right there in @twinners post, but I think I understand what was confusing me , I was thinking the trades were taking a whole week and they don't he is doing it all in one day. Thank you @improv

No problem!
