Rough engine power comparing F8X to E9X

Disclaimer - This is pulled from known information and then best guesses to fill in the "blanks". I will tweak this as needed based on feedback. This does not factor in if the F8X is underrated like it could be. This also isn't to say the E9X is better than the F8X or not. This post is designed to be helpful in visualizing the power gains over the entire RPM range. I feel like from all the posts I have been reading that the focus on the "only 11 HP" increase and not looking at the power gains over the entire RPM range.

I do understand in a race that the E9X would be in a high RPM range keeping the HP high, guessing 384 to 414; and the F8X would be 425 through 425 due to the flat HP "curve". So please don't "hate" but provide constructive or helpful feedback about the entire power range. Also, I used the 1850 - 7300 RPM based on what is known of the F8X and matched the E9X as best I could to it. I know the E9X keeps building HP beyond 7300 RPM, but I don't know the numbers for the F8X above 7300 RPM. I also know that under the F8X information there is an official graph comparison, but I think that one was pretty vague and I put numbers to mine. End Disclaimer

Flame suit on and without further ado here are the numbers and the graph. I put underscores in since I couldn't get the spacing correct with spaces.
