I find it almost impossible to dissemble any apparent improvements in my performances in bkool from changes in the sim. I say that because previously bkool seemed to favour my, err, sawtooth approach to cycling, that is power on , rest and recover, power on again. So, wittingly or not i fell into a pattern. I then had to adapt following software changes and hold power longer, something i used zwift to train for but it was an adaptation. I did deliberately choose a manual connect because i felt that provided a more accurate reflection of power/speed or at least one closer to zwift-which of course is just another sim! - and more importantly, to real life. Along the way, the sim has improved in that we have lost the worm holes, sudden accelerations etc but gained the odd anomaly though they no longer have the impact they once did. Interestingly, my ftp in bkool is near enough now to what it was in trainer road and now in zwift to suggest there has been a little improvement, but not much and i suspect that reflects actual mileage over last 18 months which, due to injury (have i told you about my knee?

) has been much less than in previous years. Look at TT whose improvement may reflect his commuting mileage followed by a bit of rest...I do think going outside and knocking out 50-60m rides at weekends makes a huge difference to fitness and stamina and i just have not been able to get out and do these rides. Darn, you can tell i am "working from home" or rather just wittering!
