what i have been doing is just cranking the resistance all the way up elevating the wheel on front and spending 2hrs on it 3 -4 days a week .
Just because you select a few comments to post doesn't mean anyone knows what you are doing.
Off hand, spending that much time on exercise sounds like you already have considerable endurance. The idea that you can assign a training volume, or training "value" between to two dissimilar exercise scenarios is silly.
At least an HR monitor would reveal the nature of cardiovascular stress. Similarly a powermeter could provide some meaningful data. As far as your goofy "dialed up" trainer setup - who knows?
