Ramp Test Algorithm

Just did . a ramp test before starting SSB1, after 8 wks of Zone 2 riding. New FTP of 197. Trainer road records my highest 1 minute power at 265, which if the calculation is 75% of that would give me a FTP of 199. I completed the 264 watt step of the ramp, so 264 would give me an FTP of 198. Anyone know what the formula is?

Believe they make adjustments based on cadence or power or something like that. As far as I know the specifics haven’t been disclosed. That said, if there are anomalies at the end then it’s not exactly 75% of 1-min best power.
