Should VC Deck Target 3x or 5x Returns and Reference Total or Net AUMs for 30% Gross IRR over 7 Years?

Guys for the VC deck when declaring target returns shall we go for 3x or 5x? Also shall this refer to total AUMs or AUMs net of fees? 30% gross IRR over 7 years would lead to a gross multiple of 6x which net of 20% management fees would result in 5x. Sounds about right to me no?
