Ask HN: Android ARPU?

hey, after finishing a week of beta testing my first game on market (casual game for female audience): Installs 914 Net payment $304.70 # paying 24 # payments 37 % paying 2.60% ARPU (all) $0.33 i'm not sure if these figures are good enough for a real launch (trying to get a publisher) or need to improve more first question for android devs: 1/ any benchmarks for arpu? 2/ what other standard metrics should i track? 3/ any idea on CPA?
