What winrats are realistic for Tourneys?

[HoRRoR]

So hello,

just got one or better to say two questions.

I wanna know a realistic winrate for a good tourney player for tournaments with different structures
- tourney like WSOP/WPT/EPT structure, 3 or more days to play
- 2 day tourney
- 1 day tourney
- half a day tourney like starting evening or something

don't know whether there is a real differnece between 1 day and 2 day, because it's hard to say

most interesting for me are winrates for like first thing WPT like and some speed offline thing like 1 day or 1/2 day
