Thanks for your comment. I understand I am not getting a true impression of the climb.
I have been giving Rouvy a look as a companion app. Up until today, I had been riding it at 100%. I was comparing Rouvy’s reality level setting versus trainer difficulty setting in RGT. I have been using trainer difficulty in RGT as a method of virtual gearing. It certainly doesn’t appear they are sending the same control information to my trainer.
Short of changing gearing, the settings do allow me to enjoy climbs with higher gradients (at least virtually).
Today, all my riding is indoors, but I’m hoping to change that going forward.
