Make sure you can repeat it and it wasn't a 1-time perfectly rested fluke. c) Leave your FTP alone and use higher and higher IF's to stroke your ego.

I think I'm at option c right now, but if I do option b and increase my FTP setting again it means I have to work harder. Damn. I think I like option a the best. Assuming I'm not sick I'll do SST tomorrow again by feel, aiming for 90% and if it comes out high then I'll have to face the music
