I disagree; or at least, I wouldn’t say something is “missing” at least.
When PD4.1 went live globally, I was having to constantly explain to our riders how PD4.1 worked and what to look for, how to react, etc. Basically, how to treat it for about that first week and a half, as our group riders were very clearly struggling to get used to the new system, with lots of splits in weird spots (primarily false flats leading up to small descents).
Now that we are indeed 1 month post 4.1 public, things have changed dramatically; the group rides I am part of, people are doing a FAR better job of riding together, and working together than they were those first weeks. Most people are definitely learning and used to it now, that much is very clear and obvious from what I’ve watched.
That said, if people choose not to learn, and blame it on the system instead of themselves willing to adapt… then yes, they’re going to have a bad time.
As Jon said; people need to learn to adapt; if you aren’t willing, then the problem lies with [you], not the system. Is the system perfect? No, and nobody is saying it is, but it is very clearly far superior in a majority of aspects than the former systems.
I’ve said it once and I’ll say it again: People here seem to act like Robo Pacers are meant to be some perfect image solution in their minds, allowing them to ride a perfect constant Zone at any given moment. They aren’t, and they never will be due to the massive variance in people riding with RP’s, varying routes, etc.
If you want perfect zone riding, set up a workout and run ERG. Robo pacers are never going to be a perfect pace for everyone, at any given moment each day.
On flat, (generally more popular) courses, more, heavier, high wattage people will join the bots, and pull the packs to [consistently] higher numbers.
On stranger, more hilly routes, there will be far less of a populous around the RPs, and the pace will be highly variable.
Once folks get it out of their heads that RP’s pace is unaltering, can be biased heavily, by the size of the groups around them and the style of riding, this topic will fade away and/or people will realize the RP might not be the solution to their “problem.”
RP’s are designed for big-pack riding majority of the hours through the day. That’s the only part about them that should be considered constant.
Beyond that… every day, and every hour, should feel different than the day/hour prior; and the data should [and does] only prove that.
There may be a solution however to this.
Something we do during our group rides is tighten the fence, or pull back our front-riders to settle down the pace if they begin pushing.
If the RP’s could potentially have the “brain” to realize that their moving pace is higher than that of which it should be, and slow down / speed up to bias its own power to aim for a specific speed… some of this issue could potentially go away.
That does however greatly increase the CPU demands of whatever is running them; more than “increase watts on inclines”
