Wh is a unit of energy (1 Wh = 3.6 kJ) and by nature cumulative. And cumulative units can't peak, so Whp [sic] is impossible as a unit. What you really meant is Wp, as W is a unit of power (1 W = 1 J/s), which is a momentary value and momentary values can peak.
Is mayonnaise a scientific instrument?
