Any one on plus experiencing this??

I'm working on a goal using sol xhigh that usually keeps working for an hour before 5h limit is done, no issue so far "except the 5h itself lol anyway" as I reach 10% remaining of 5h limit I didn't think much of it until I literally blinked and that 10% became immediately 5% it didn't even go through 9,8,7,6 just jumped straight less than a min later it's 1% then it's 0% all immediately??!! That 90% lasted an hour no issue I didn't do anything new so theoretically that last 10% should have lasted 6min not 1min I'm not really complaining but that was weird I understand it may have been a tool call but that's still a little idk how to even describe it.
