I did some calcs.

Core 3.55
Glass 5.2
Net 11.35
Resin would be 2.6

Resin % of glass 50%

Am I a bit high or is this okay. I had saturated breather, so could pull more with more breather media.

Easy way to hit a 50/50 resin to weight ratio is to match the weight of the dry cloth with equal weight of epoxy. So if your digital scale weighs 300 grams of cloth you should plan to mix 300 grams of resin.

600 grams total. 300 cloth, 300 resin. That’s 50/50
