if you try to not do it even as intervals you even try to just combine those 30 minutes into one power output at all you won't be able to put out the same amount of power if you just did it in One S one one go 30 minutes there probably then you would be forced to do maybe to bring it down to 280 270 if it was 300 for example what's when you did it as as 5 minute intervals maybe even more down
