I think that would be very difficult. When we're two or more riders in a group, we unconsciously utilize the on/off effect. I thought about going into time trial mode if one should go for a solo breakaway, but what if e.g. you gained 1 minute and then couldn't keep the pace up? If you don't wait for the others to catch you, then you would have utilized the on/off effect.
Or just take it like a man as you would if you had Tom Doumelin/ Tony Martin/Brad W up your chuff in a TT or if your glorious solo break ended when caught by the bunch 50m from the line....no amount of stop/start is going to help you there.....If nobody exploited the weakness in the tech it would be a leveler playing field.
When going through and off in a group you naturally get a fluctuation in effort but the aim there is to smooth that as much as you can as you don't want spikes. The harder you make it for the man behind you to come through means that he doesn't come through, leaving you to battle the wind. with two Bkoolers jointing see/saw riding as a reaction to each other its just more of the same - seeking to exploit the tech.
Not sure why its a problem to just keep the pressure on or ease a tad if your shagged..thats a bit different to no effort ease right off to full gas on off.
Not having a go at the proficient on/off'ers but I cant really see the point other than to gain an advantage to who is the best at on/off. From what I can see the best on/off'ers are amongst the strongest riders anyway, by a margin, so why no just ride 'fair and square' so to speak and see what the result is.
Repeat ...not having a snipe here. No offence intended. Just cant square it away in my head.
