i didnt want to say anything but when you see the charts side to side something does look odd - could it be an unusual style of riding or a faulty machine ?
have you compared other charts to yours Mr AAAC ?
surely other charts would be smoother like yours ( maybe not such high numbers - for obvious reasons )
do you think you could replicate his chart ? or would it not be possible
sorry if i aint making sense - i recently recieved a blow to the head ! right there - where it hurts

Looks like Jacob was lucky to beat Pep today if you compare their speed graphs:
The orange line is at about 75 kph and the red at 50 kph

Pep's graph looks like some kind of music score!

In reply to @berty bassett - no, I don't think it's possible without some kind of "fault" to maintain an exact flat-line speed like that

P.S. Also, if you look at Pep's ride on Bkool, his power and cadence flat-lined in exactly the same places as the speed too

so would it be possible to get to a high speed , lose external power for a bit , then regain and repeat ? would that create the same pattern - if possible
like a faulty power adaptor ?

I've had a faulty connector on the PSU to trainer plug, the socket was ok as proved with a new PSU. The movement of the trainer was breaking and making the power. But I have never run a session with it in place.

I think this might be something like what's happening. I seem to remember @AAAC 76C experimenting with turning the power off on his and the speed just flat-lined until the power was restored.

There's no doubt Pep's a really strong rider, but Bkool really do need to get their act together with filtering out rides with glitches like this (and obviously the ridiculously high power rides) from league results - it's ridiculous

I was going to question the issue being the trainer. I then remembered Pep has a Pro. They give Power, Speed and Cadence without the need for extra sensors.

Yeah this looks like a problem with the trainer/power. But do they put a restriction on loss of signal from the trainers in the SC. I know there is the facility to do so as we have it in our CG league.

I did wonder if he was going into erg mode. He gets up to speed, high cadence and steady power then goes to erg. Holds as long as he can then drops out to rest with resultant drop in power and speed. Rinse and repeat. He's a strong rider so it ends up being an interval session. Easier to achieve on a course like this with slight gradients.

Anyone have a connection to him? He may have found an efficient and effective way to race on bkool

They have the loss of signal value set at <=200000 which I assume is the maximum value so equivalent to no restriction. Having said that, it's perfectly possible to have a loss of signal without the flat-lining of speed, power etc. if you just lose the internet signal temporarily and it comes back again. Pep's ride has a lost signal value of 481 for that ride, whilst AAAC's has 1884, but AAAC doesn't have any flat lining and looks perfectly normal

 

[berty bassett]

he is certainly one of the best/strongest riders that is why i wondered if anyone could replicate his graph

I think if you're using ERG mode your watts would remain pretty flat but not sure that would also apply to speed and cadence like on Pep's ride above would it? They would still vary in ERG mode?

I might try putting my remote control power plug - which I use to switch on my fan - on the trainer and see if switching it off for a minute and back on again during a ride gets similar results....

On a course like this, flattish sections and descents, I would have thought if you hold constant power, speed would stay fairly constant too. I see cadence as a made up guess by bkool based on speed, so if other 2 remain flat I'd expect cadence to stay flat too.

Never used ERG mode mind so could be talking rubbish

If that works I may be adding that set up to my artificial doping too

Have you ever tried keeping your speed EXACTLY constant? It really is impossible - there will always be minor fluctuations. Below is a screenshot AAAC put on here a while ago which is one of Pep's rides where I think ERG mode WAS being used - note the fact that power isn't completely flat, but fluctuates slightly (as does cadence), and the speed is all over the place. Also, I'm pretty sure I remember reading that the BKOOL trainer does have some kind of cadence sensor built in (albeit a pretty inaccurate one!)

That's my theory out of the water then

Never noticed flat lining on anyone else's rides so maybe we'll only ever know if we ask Pep. Let's convince @AAAC to contact him after he's had a glass or two of red vino
