You would find supra-threshold power efforts much more repeatable at a higher cadence.
90rpm for me is still too muscular for upper end. 92rpm is the minimum 'clearing' rpm. but 95-100rpm transforms the effort from being a strength-endurance demand to predominantly aerobic. My legs (muscularly) feel fine albeit fatigued from the workout as a whole rather than from pedalling alone.
If you can get some cadence drills in and get comfy at 100-110rpm it'll help hugely. As does 'spinning up' before the hard bit of the effort begins.
If I'm doing an effort at 110% for 3-5 minutes I'll spend the 30 seconds prior bringing my cadence up from 85-90rpm to 100-105rpm. Else you end up spending 10-15 seconds putting out way more wattage than your target to simply maintain your cadence and you then carry that fatigue for the entire duration of the interval.
Cool beans - will have a play on the Wattbike this afternoon.
Thank you very much.

And whilst I can push relatively high cadence (90rpm is fast, but 100-110 should be fine), I don't like it because it feels far too aerobic for my tastes.
