Compare Polars

The help page seems clear enough

Cell H21 says 80 is the speed in kph at which the sink rate is measured.
Cell F19 says .62 is the sink rate in mps

The glider weight is included in the wing loading column.

I don't have much interest in discussing failings in these calculations because I'm pretty happy to have the spreadsheet as it is.

OTOH, if you have energy to put more gliders into the data set, that would be interesting.

ok, I'm not getting the "cell says", perhaps not so up on xls spreadsheets etc. I am working with the CSV exported data...

what is the "wing loading column?" Is that G/F? What units?

what are the units for the rows where the units are specified as "kts?" Are the airspeeds all in kph for all rows, sink rates in mps or kts as stated?

Ok, the .csv thing explains your problem.

The .xls file is not just a spread sheet, but rather a workbook of sheets that work with Excel.

Without that, I can see your frustration and can offer no help.

You are kind of in a dark hole of your own digging.
Suggest you stop digging and find a copy of Excel.

Choices:
1) Buy a copy of MS Office / Excel
2) get a hooky copy of Office/Excel
(may be OK, may contain malware unless you know and trust the source)
2) Download and try Libre Office
This is a free/open source office suite that provides the same
functionality as MS Office. There are versions for Windows, OSX and
Linux

I use Libre Office on Linux systems for all my spreadsheet and word
processing needs. By and large it 'just works' for spreadsheets including
Microsoft XLS spreadsheets, but might have problems if these include VBA
macros. I've never needed to load a MS spreadsheet with VBA macros so
can't comment about that.

Open Office is another decent free one if you don't use spreadsheets enough to purchase a program.

Seems to work in Numbers on a Mac.

I tried it last night on the Libre Office (5.1.6.2) that come with Ubuntu 16.04. No joy, the graphs didn't get through.

It is nice to know that is works on Numbers on Mac.
That provides a second option.
