Is This Recommendation Suitable for All Fund Sizes or Just Small Funds Considering Power Law?

I have checked your Investment Volume and Follow-on Chart. My question is whether this recommendation is just for small funds or for any fund. It seems the only way if you have 5M€-15m€ fund and 2 GPs but in case you may raise a higher fund size and taking into account the power law couldn´t / shouldnt the # of investments be larger? for example +20 investments for series A fund.
