# which loop should I use (while loop or for loop) to find the max power for all steps from the begining to the last step for random points ?

first, below I deployed two random points. second i measured the power in each moving step. third I measured the max power in from each 20 moving step and this random point will re-move another 20 step moving. My question is that, can I find the max power for all moving step instead of measuring the max power for each 20 step and the measure max power for 20 step and so forth.
Thanks in advance for any help.
