Is it possible to have a difference in stropping technique between blade sides resulting in a sharper razor on one side versus the other? Maybe putting a slight curve on the edge along its entire length?

I'm noticing my razor appears sharper when I do the right side of my face compared to my left. There could be a few explanations for this. I suspect it's because the left side is my off hand, but want to get your views on the stropping. Do I need to look at that too?

Thanks for the advice!
