I'm not going to claim to be a HR training expert. I've used HR-based training for 3 years now and I've learned that it's valuable but also not to use it as the only tool in my training.
Case in point: I'm going through a fatigue phase right now where my HR is actually lower than normal (say by 15-20 bpm at 35 km/h on flat ground) but I can't generate as much power. I feel like crap but if I went by HR alone I'd think I had some reserves. In my case I have to trust my body and not my head.
To determine fitness I look at the long term trends. For example, I ride a fairly consistent set of routes each week. By looking at the trend over the last 4 months with the Polar software I can see that my average HR (for a ride) is dropping while the average speed in increasing.
Just to throw a wrench into my training I ordered a PowerTap this week... I think that's the ultimate window into your training.
