Good stuff.
Keep in mind I have no qualification to be advising anyone really, but I’ve done indoor and outdoor everesting rides and I don’t mind throwing in my 2 cents worth.
If you want to be a diesel and prepare towards an everesting ride in a few weeks time, my initial thoughts are that the rides / data you have posted don’t make me automatically think “that’s an everesting training plan in action.”
On intervals.icu, how does your chart look for 90m, 2h, 3h and 4h?
I have no doubt you can do an everesting at the end of this month, but I also know that pushing out time to exhaustion and building endurance are good training objectives for everesting rides. Doing that with 1 hour sweetspot and 6x2’ VO2 workouts would need multiple workouts per day (Maybe you are dong that? There is certainly time to, with 15h / week available).
Whilst there isn’t a lot of this month left to move the needle much on those things, with 15 hours / week to play with, you have the opportunity to at least do multiple 2 hour plus workouts per week. They are the rides that, imo, will move you towards your stated objective.
If I was to train for another everesting, here is how I would use ~15h per week. I would primarily keep building consistent tempo / sweetspot volume to push out the time to exhaustion and drag up the floor and let TR AI take care of the FTP setting.
1 x 4h ride per week (I’d do that outdoors personally) with indoor rides along the lines of Gammon and Polar Bear +1, along with something like Dorr+5 once a week to keep the top end touched, making up the rest of the hours.
I would do two workouts in a day a once per week to get more used to being on the bike for longer periods of time.
I would stick with the principle that consistency is king and if I found that this session was too hard for me to do the next one properly, I would dial back the intensity or frequency accordingly. Against some conventions, I would rather ride every day than take a rest day when training primarily at these intensity levels.
Maybe take a look at the sweet spot progression thread on this forum for more on TTE and similar training and its benefits.
Also, I would be as certain as I could be that I had my position on the bike as close to perfect as I could get it. There is nothing like a mostly seated long ride that gets you really close to the limit to magnify the slightest bit of discomfort from, say, too long a stem or a cleat that isn’t quite perfectly aligned (ask me how I know about that one!).
