If it was me, I’d do a ramp test. Ramp tests are good for the soul.
Failing that, calculate 95% of what you think your current FTP is and manually input it. Adaptive Training and a bit of your own judgement will do the rest.
No point wasting 14 days messing about. Get a realistic FTP in now, then schedule a ramp test for 4 weeks time or so and use AI FTP Detection then.
