I think you're right that the spec is written incorrectly. I believe it should describe that the multiplier on T1 doubles with each reset. This is not clear in the existing text. So for example, if 8*T1 < T2, then the third reset is 8*T1, and if 16*T1 < T2, then the 4th reset is 16*T2

Otherwise said, MIN(2^N*T1,T2) where N is the repetition iterator.

[e-mail] would probably be the right place.
