"1 SP 1 Vote Scheme:
Advantage: Simplification'

"Every user only votes for 1 witness, big users will have to split stake to vote for several witnesses. This is easier for new users to grasp and identification is established. Single party has to split stake to vote for many witnesses."

This is incorrect. What you describe here is 1a1v, not 1t1v, which is how it is labeled. A better way to understand 1t1v is that witness vote VP depletes 100%. Thus an account can vote however many different witnesses they want to, but can only vote each SP once, because SP already voted with has no VP remaining. So the account can vote all their SP for one witness, and be done, as you suggest above. However, they could also split their SP into 30 witnesses. If they do that, their SP is split amongst the witnesses they vote for, and they do not vote any SP for more than one witness.

For example if they have 30 votes, they can vote that all for one witness, or 1 vote for each of 30 witnesses in the above example, or any variation between, but will not have more than 30 votes. [I am using votes as you do throughout the post, meaning Mvests.]

Thanks!
