Putting numbers into Workout Creator and getting an intensity factor reading across the 4 intervals, I don’t believe anyone should be able to do these at more than 105% of threshold.
This workout expects you to do 32 minutes of work with only 3 2min rests. If you can do that at “108%”, then you probably need to re-test your FTP.

The intensity factor is 1.03 but the workout length is only 38 minutes. I don’t understand why you think that a rider shouldn’t be able to complete that.
