Why is it easier to locate objects when you observe them under low power than under high power?

You can see what you are doing better in low power in high power, so you can center the object first before you switch to high power to make minor adjustments.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
