The best way to "optimize" for dating is to: 2) Become hot and 2) become happy.

A happy and hot person is someone more people want to be around. If more people want to hang out with you, you have more options, become less needy, become more clear headed ... list goes on, it's a virtuous cycle.

Using the scale of 1-10 is not great, but its mildly accurate... most people, via work on their character, attitude, physic, lifestyle, finances, fashion, etc. can bump themselves up as much as like 3-6 "levels" on the "hot scale". Seriously. Some people can go from like a 3 to an 8. One's life changes drastically when this happens.

Doesn't matter if its a dating app, bar, friend of friend, w.e. It's much easier to find a partner if a person is very satisfied with who you are.
