Thor ragnarok Power Gain during sp3

So I was using the new buffed Thor ragnarok and noticed that when I reach 40 hits and get the power gain buff and use a special 3 while the power gain buff is active I am not getting any power after the special 3 While the power gain buff is still showing up and loading.

If you have 0 power, it'll give him a relatively rapid Power Gain (which you can do by activating SP3 at 34-39, 74-79, 114-119 etc. hits)
If he already has max power, it won't do anything, because I don't think his current power affects it - only the power he had on activation.
