Sorry but it doesn't seem legit.

This is how your fuel gauge varied:

Due to your original speed and height, you should have spent more than 100 m/s, so there should be a noticeable difference.
Same problem for the return part, you have around 15-20% of fuel remaining. 17% of fuel give you 567 m/s of ΔV, which is barely enough to come back to Earth. And this is with a perfect trajectory, yours is very inefficient so there's no way you could do it like that.
If you attempt the ranked mission we can help you but please do it without cheating. Also, be careful not to crop screenshots like for the two lasts, we clearly ask for non-cropped screenshots.
