well how many people (girls) do you have on contract or available for shooting?
there are several options that can influence how often something might be filmed - each girl has option how many scenes can be shot per week (if not done manualy), then there is happines score, popularity penalty check (whether she can shoot another scene already or not) and scene likeness rating on producer settings (and who knows what more elsewhere that i did not find yet

) => right now with 4 studios and about about 130 girls (+-80 contract, 30 agency and 19 freelancers and out of these numbers only about 30 are available for shooting each day) auto production of scenes is making about 2kk per month on scenes so they are shooting as planned 19 out of 19 scenes per week (studio shooting days = 5 / 4 / 5 / 5)
also i´d recommend not to have shooting set for each day (ie 6 days per week) as if i recall correctly it makes studio stuff unhappy and people likes to leave or ask for health break (this one might be just random though) - that might be issue if some crucial staff is missing in studio
