SCBTC - NoobQ: What's wrong with price range tool?

Hello Folks. I was trying to analyse SCBTC chart and came up with a basic question. Please help me understand why the price range shows different percentages when I draw from top to bottom side by side with bottom to top.

I was only trying to understand how much a trader might have lost if invested in SC at its peak price Vs how much he would gain if investing now and see a ATH again. Something does not seem correct here.
