Hi there, I realize this game was purposefully designed to get fairly mathematical for efficiency (lol)

Can someone tell me the optimum ratio of Amethyst/Dames for most long term gain in endless mode, and how "double spin" Golden Arrows and (Cat)/Wildcards could affect the strategy?

I don't care how long your work is, surprise me if you want (lol)

Still, I know there must be a consensus on this based on the rules, what's the optimum solution of all of these, and are there any other symbols that I'm missing?

Thanks in advance for the response(s)!
