Something else to consider is that you're not supporting your weight on a rowing machine, as you are when running, so your heart rate is naturally going to be lower for a given effort. That means you'll need to adjust your heart rate zones accordingly.
On the erg you can get just a high a hf as in running, but it takes times to learn how you can go hard enough to reach that, if you want that ofcourse.
The most important number by far is the pace or watts, those are the same in a different way presented.
You can go faster in two ways, makes the stroke stronger, push/ harder or make the recovery faster/ increese the rating, combining the 2 is the most logic.
It would make sense to increese the rate if your pace goes up.
Drag is of importance but not that much, use what feels the best. For sprinting that will be a bit higher.
