It's more about synergy, not math. I have a 300 wpc Mac but usually am using my 10 watt triode. Running out of power can ruin a speaker and/or your experience but quality is much more important than quantity.
My math was a generalization but you do need a frame of reference on these things. Generally speaking you gain 3db for doubling your wattage is a great way to understand why going from 40 to 60 watts is virtually inaudible all other things remaining equal.
