You don't vote for anyone and thus by default 'do not approve' of anyone.
1)-Top 101 delagates with most casted votes 'for' ('for' being the only active choice) are
in (for that round), correct?
2)- If you have transaction 'transfer 50 BTS' which is worth 50 votes:
-if you vote for candidate #20 only, candidate #20 gets 50 votes
-if you vote for candidate #20,#21,#22 - candidate #20 gets 50 votes; candidate #21 gets 50 votes; candidate #21 gets 50 votes
That's what I gathered (more logical is #20,21,22 to get 50/3 votes each but I understood it is not how it works)
