Older Rocketman Parachute Weight/Descent Rates

[rodbender6062]

Does anybody have the chart that shows weight ratings/descent rates of the older chutes...ie R9C, R12C,etc?
Thanks

As a side note, the number refers to the standard size in inches, so a RC3 is 36", RC4 is 48, etc. At least that's my recollection of it. I used the 'insert data from picture' feature of Excel to convert that graphic into the table below. That is one of the most useful new Excel features introduced in a long time!

Would you extrapolate the rc values please. Not quite following the logic. Seem to be suffering from a bout of acalculia.

3:36
4:48
7:?
9:?

thanx

This seems to be a mystery. Is an R7 - 7' or 70" or 72"? R18 - 18' or 180"?

Here's what I have based on what Buddy told me at BALLS a couple of years ago:

The number in the chute size rather than being feet is the first digit of the size in inches, but the sizes are based on feet. Of course I could be remembering things incorrectly, but based on the chart above it seems to make sense. I think it was because they don't have the same descent rate as traditional chutes they did not want people thinking their 72" chute was equivalent to a regular 72" chute.

Thanks Tony. That makes sense because it doesn't make sense.

Maybe my version of Excel is outdated, I'm not able to insert data from picture which is a bummer.

I have the MS Office subscription. (Used be to called Office 365). After looking around online, it looks like the feature is available for Android, iOS, and MacOS, but not for Windows. I have both a Mac and Windows laptop and confirmed it's only on the Mac version of the app, at least as of now. It looks like it was available on mobile first, and now MacOS. I have to believe it will eventually make it's way to Windows, as it's such a useful feature. I've found it easier to take screenshots of tables on webpages, crop them to the area I want, and then use the insert data feature, instead of trying to copy the table text and use that directly.

under the dropdown menu that icon is labeled "Data from Picture" (on the Insert tab)
