If you really want to understand the relationships there is a good book....
power Meter Handbook by Joe Friel. Velopress
If you want to determine just how much of an estimate a ramp test is..... go and try to ride your ramp tested FTP for an hour.
I know I can’t get anywhere near that number, but I’m working on it with my coach.
I have an ERG file I use for my ramp testing. So same exact test every time. The results do show me improving but I’ve learnt that with wheels on the road the number I can actually achieve will differ.
oh and the book will also show you how to determine your efficiency. You’ll be able to track your power increasing for a given heart rate.
point is, that vO2 may be pretty stable but there are many gains to be had even with that limitation in place.
all the best

Edit: I’ve been surprised by using a coach. Some of it is counter intuitive.
l’ve burnt more fat in the last 4-5 weeks than the last 6 months, despite the rides being easier in effort.
The book has helped me understand why.
