NP 14% higher than FTP? How

My Average ride power was only 209 on a 49 minute ride. I did a big surge up a short power climb, but how am I getting NP of 312?

I feel it might be the formula getting confused by the surge. It was 900W for about 40 seconds which is about 10w/kg.

My FTP is 274

Ignore HR, it wasn’t reading right today.

NP and IF are meaningless when sprints are involved.
