Idk about the others, but have you considered critical mass for the first one?
a couple of English words needed
Imagine you act in a team versus another team. You look at them and assign them scores. And then you pick your inflatee.
1 How would you call a score telling you how important it is to (over)inflate a character?
2 A score telling you how easy it is to (over)inflate a character?
3 And a score telling you how good a character is as inflator?
By how 'important' it is to (over)inflate a character what do you mean? Like their 'threat' level on their team vs yours? Going with that here's a few silly ideas
1. Detonation Desirability Level; Inflator Threat Level;
2.Ultimate Stress Level; Terminal Stress Level; Inflatality Level; Poppability Score; Pressure Management Ability;
3. Pneumatic Power Level; Pumping Power;
All the ones I can think of atm but if I come up with more I'll toss them up
