erg data: translating and recording
It's hard to get exact data for individual rowers on the water. Unless a pair is so badly mismatched that the boat is being clearly pulled around to one side or another, the only way to really tell who's more efficient at moving water is seat racing, which is itself rather questionable (more on that later). Even with seat racing, all you and your coach learn is who is faster.
With ergs, though, you can get individual data on power, time, splits, etc. That's why erg tests (though not as important as seat races) are such a big deal. A rower's 2k time is what he sends out to college coaches to get recruited. During winter training, your coach is going to want as much individual data on each rower as he can get--and your rowers will probably be very interested to see how they're doing, too.
The things you'll want to write down:
Time:
Pretty self-evident. Keep in mind that times on ergs are almost always going to be slower than times on the boat because it's only one guy against an unforgiving machine as opposed to eight guys pulling together, especially if you have a nice little tailwind or current helping you along.
Also what the erg doesn't take into account is, to some extent, technique, but mostly weight. Heavier guys have an advantage here because they're generally going to have more power. If that power isn't enough to justify their extra weight in the boat, though, they're going to slow the boat down. I've provided a nice little calculator here to show the weight adjustment ratio, but every coach does something different. Mine goes off the 165 lightweight limit.

Split:
How much time a rower takes to cover however much distance the erg is set up for. The normal distance is /500m and is what most standards are based off of. For instance, an average split of 1:45 for a 2k will be a 7 minute time flat.
This is very important. You will always write down the average split. Sometimes, if your coach is as detail-oriented as mine, he or she's going to want you to write down the average split per certain distances. For a 2k, for instance, if you have the machine set up to take the split every 400m, you're going to have 5 average splits, one for each fifth of the 2k.
It can be useful to know to see how your rower does--does he pull with fairly consistent pressure all the way through? (ideally, yes.) Does he start out strong and then peter out? (NO DON'T DO THAT) Or does he speed up at the end? (a little bit here is good because it mimics the sprint you'll do during the last 400m of an actual race. If he speeds up more than 4 splits though, it could mean that he's not pulling hard enough in the beginning.)

Rate:
Just the same as on your cox box, how many strokes the rower's taking per minute. On a 2k test, the novice rower's rate should be somewhere around 28-30. Any slower and he's not getting maximum power; any faster and he's probably--though not definitely--rushing his slide.
---
Watts:
Unit of measurement for power expended. Basically, how much pressure the rower's getting on the drive. It doesn't get as much attention as the split, but if anything it's a more accurate indicator of how well a rower does. Splits can lie--you can have terrible technique and still pull a high split if you're super athletic. It's much harder to produce high wattage without good technique because at least 70% of your power comes from your leg drive (or it should, anyway. I don't care how big your guns are, your legs are still bigger). If you open your back/break your arms too early, shoot your tail, etc., your watts will go down.

So to actually get to the memory, first off, go to the home screen (if it's still alive, just hit back. If the screen's dead, hit buttons until it turns on.) It should look either like this:
in which case, obviously select memory--or it will look like this (this is the way mine looks):
in this case, hit More Options (not Information, which seems counterintuitive, I know). Memory should be on the next screen that appears.
What will then appear is a list of all the workouts that have been completed on that erg. It's chronologically backwards--so the first workout is the most recent one done, then the second workout is the next to last workout done, and so forth. Use the 2nd and 3rd side buttons, next to the up and down triangles, to select the workout necessary and then hit the 1st side button to expand on it. You should then see a screen like this:
So there you have time, meter, split, and stroke rate. Notice how the first line is boxed in? That's either the total (for time and meters) or the average (for split, watt, and rate) for the entire workout. The lines underneath are the data for each part, however it was split up. So this workout was by distance, 6000m, and the erg was set up to take data every 1200 meters.
To get watts, just hit the Change Units button in the far left bottom corner and instead of the splits you'll get watts.
So in this case, you'd want to arrange the data set by meters and have it set up something like this:
Rower A:_erg no.__1200m____2400m___3600m___4800m___6000m___total
____split:_______1:24.5_____1:25.0____1:24.2____1:22.6___1:21.7___1:23.6
____time:________3:22.9____3:24.1____3:22.3___3:18.4____3:16.3__16:44.0
____rate:_________41______40_________41______41_______46_____41
This is by no means how you have to take down data, I just find it easier to do it this way.
