How acurate are these machines? If it said that I burned 200 calories in 20 minutes, how true is that? Do they tend to be more conservative or generous?

It's a stationary bike. Avg RPM 72. Avg HR 155. 7+ miles.

It depends on your weight, if it lets you input it. The heavier you are, the more calories you burn doing, well, anything (so long as you aren't eating at the same time!).
I've noticed that exercise machines do tend to inflate the amount of calories you burn, but not too badly. A rule of thumb I use is 85% of what it says I burned, I actually burned! So 85% of 200 is 170.
This is just personal experience. It can also vary from model to model of machine.

I'm not sure what parameters those readouts use to figure those numbers out.
If you incorporate exercise into your lifestyle and use those machines for your cardio workouts you should notice something over time. Your body 'conditions' to the activity.
If day one you are doing level 3 hill on the bike and your heart rate is 145. By day 200 your body will have conditioned, where it can accomplish the same exertion with less blood and probably your heart rate will only be 120 doing level 3 hill on the bike. Hence you will burn less calories when you are conditioned if you are not challenging yourself with a tougher workout.
However, I am not inferring you that need to workout longer than you already are when you are in shape. You can just increase intensity instead to keep your metabolism stimulated.

Hmmm...I've heard that your average male jogging briskly for 40 minutes can burn 650 calories, so it sounds like that digital readout is somewhere in the ball park. Is it exact? Probably not. Too many factors to consider, like your gender, age, fitness level, body fat percentage, metabolism, etc. In this case, if you were jogging I'm guessing the readout is being conservative and if you were walking the readout is being generous.

depends on the machine, if u got a new one, it is pretty accurate, and if it's old, well its not as accurate....
