Fund Terms (Economics)

What are the most common fund terms between Searcher and equity Investors (for Self Funded model)?
I have mostly come across c. 8% pref with or without catch up for Searcher, and then 65% of excess equity created to Searcher and 35% to Investors.

Is this the norm? Are Investors OK with giving the Searcher 65% of equity returns - I assume yes provided that they are offered a 25% IRR, but still I would expect getting a few frown on proposing such.
Is it not common with the classic 2/20 PE compensation model?
