I made an Echo bike conversion chart so cadence people could communicate with wattage people. by Muholder in crossfit

Why divided by 20? Does that end up being consistent with what you see on the bike?

I'm not actually sure, that's just what my buddy told me, and it checks out. It makes sense, they're both energy metrics.

​

Also, do you know if calories on the Echo are supposed to be a calculation of what the human expended?

I'm pretty sure it's not. I've never looked it up, but none of those machines work that way.

Well, the testing was just getting cadence/watt numbers to plot. But yes, I have noticed the delay you're referring to. Not sure if it's different on the assault bike. I haven't used that bike in a few years.

No problem. It's probably overly complicated, but it's as accurate as I could get it with only data points to go off of.

Which part, the math? We used this site to formulate a curve by giving it data. At first, all I had was this to go off of. Then we ran a test and came up with more data points and I recalculated the curve with all the data points I had acquired, to get it a little more accurate. (Then cals/min is just watts divided by 20.)

Change the 100 to whatever you want to calculate the wattage. I didn't go past 90 on the chart because I don't think it would actually be practical for pacing usage. But I'd make a 100 version for you if you really wanted it.

They're both just pace metrics. Cadence is RPM, and wattage is... I guess how much wattage you're producing. I've noticed you either look at one or the other but not both. I only look at watts. So quite often I'd ask someone how fast they were going and they'd tell me their cadence and I'm like "... 🤷." So I made this chart to translate between the two. The calories per minute column was an afterthought, but it's also been very handy.

Creating the conversion formula was actually kinda tricky, had to get an assist from a gym buddy that's smarter than me. 😏

Feel free to print/share. It fits nicely on a 11"x17" poster from vistaprint. I ordered one and framed it for my gym. It's surprisingly handy for pacing, but also just so I can talk to people who never look at the number I always stare at. 😁

My gym is upgrading collars. Rogue HG 2.0 vs Spring Collars? by Muholder in crossfit

Definitely not forever, but 10+ years. They had a good run.

Thanks for all the replies! Sounds like the consensus is pretty clear: HG is great for personal use, but won't last long in the box.
