Actually I would have love to display the screenshot of the changes in my steem power but the screenshot wasn't long enough. I am glad i check in my account after the power using cotify bot while making the calculations i discovered the precise before and after of my steem power

@6:32pm yesterday I performed a power up of about 132.170 steems and at around @6:38pm i checked my balance and it was 921.927, so doing some mathematics 921.927-132.170= 834.757, so this is the exact amount that was left in my wallet before powering up.
