Test any values using the Excel first, then make an ‘formal’ suggestion.
I’d like to have a TestFlight beta, however I’m not sure there are even enough players with an Apple device (given 📲 Poll: iOS or Android )
Possibly, yes. But with an Invasion boost rate of 300% (+50% on average due to difficulty), only a 10% penalty for each repetition, and 3 ‘free’ repetitions (this is an upcoming rule), you’d have to play the same mission 38 times to start eating into your actual collected keys. So I don’t think it’s a consideration, practically speaking.
