I'm sorry Ron but you are not understanding how the Vote Accruals work.
In your example, on Day 3 you do not receive a 100% upvote at 6AM. In fact you would not receive a vote at all because only 11 hours has passed since your last vote and there is a 12 hour minimum between votes. If you posted at 7:01 AM on Day 3 (extra minute to be safe) then you would receive only a 50% vote - not 100% as only 12 hours has passed since the last vote which is 50% of a day.
There is not fixed time intervals, there is only a minimum time for Vote Accruals to build up between votes. This is a seperate feature to the Precious Gems which are just to ensure that at least every 2nd post needs to be relevant content on the tag.
I hope this makes it clearer, but I encourage you to test out your abuse scenarios because we will be watching and if you find one then we will look to address it because we don't want the community account to be abused.
