The point I was trying to make was that the time you use to perform the calculation may change whether there is an "experience" on behalf of the calculation. Without specifying the basis if subjectivity, you can't rule anything out as far as what matters and what doesn't. Maybe the speed or locality with which the calculations happen matters. Like the water drops: given the same amount of time, eventually all the water will evaporate in either case leading to the same end state, but the the intermediate states are very different.
