I put a third of the pvt and all of the spy towards the countdown. Except the one towards getting my clothes off.
I haven't yet had a point where I get two privates on the way towards countdown, but knowing me... I'd forget to subtract the previous privates numbers from the total and accidentally put extra towards the total.
Which is why I don't do all of the pvt.
(Examples of what I'm talking about:
I get a pvt that gives me 135 tokens and spies for 24 toks. 135 /3 = 45, + 24 = 69 tokens subtracted from countdown. As they can't see, I might just throw in an extra token to make it an even 70.
If I get another pvt, and afterwards I note that the pvt total is at 372, I might forget to subtract the 135, so I'd put 372 /3 = 124 towards the countdown. x.x
Why by 3? cause it's 60 toks per min, and this way I can get up to 3 pvts towards the countdown before I'm giving them more than I've gotten.)
