If curve is linear like belownumbers shouldbe in order. 3 things thatI think can give you the numbers in different order .
1 data colection to the Copy/Paste Cell
2 calculation
3 curve .
One of them it my have couple bugs.
Curve can influence the numbers. If you taper down at HI RPMS then your numbers are going to change,If you use a curve similar of
ROB posted here.
If you use something like I just test here then they should be in order.I just used 12F683_CDI_v0.9b3 excel file.

LOW RPM= Hi number
Hi RPM= Lo number

So... in order to make sure "numbers are right" make a linear curve , spread the numbers as equal possible over the RPM range.
Look in to the table data and you should all numbers in order.
After that go ahead and create your desired curve.

In this particular example that first number is an issue....can be a data colection,calculation .
Take a picture of the curve and posted here. My be able to pinpoint better.
Like I saidcan be one of the 3 or all 3 of them with the new version of the file.

Thanks
