Not sure if I understand your question correctly, but here are some numbers based on my understanding.
From your example. You will lose .14 after each 100% vote that you cast. So in total you will cast 136.5$ worth of votes to get from 100% to 50%. Calculation are not exact but pretty close I believe. Based on current steem and sbd price and considering 25% curation, you will make 51.1875 SBD and 61.67 STEEM (equivalent to 52.23 SBD ) . This means it should be equal to 103.149 SBD.
How do u come up with this table
Specifically how do u know how much % VP we lose with every vote?
you lose 2% VP everytime you vote at 100%, that reduces value of your vote. It takes 2.4 hrs to recover 2% VP so you can cast 10 votes at 100% everyday without ever running out.
Yes, but only if you vote precisely at every 2.4 hrs.
irrespective of how much u vote, it will always recharge at 2% per 2.4 hrs.
Yeah, but you can make exactly 10 full 100 % votes per day only if you vote exactly every 2.4 hrs, right? :-)
yes.
Your vote value reduces by 2%, but at 50% votevalue a reduction of 2% is effectively 1% i.e. to 49%
yes, but that is already accounted for in @mightypandas table above
