Take the voltage data you posted above and place it into that array.  From what you said above, I think you already did this?

the problem is there is ALOT more data than is available in my array   also the charge curve and disscharge curve are different

Let me be very slightly more specific: take the data you posted above (not the mostly empty results you just posted), select the values that correspond to entries in those arrays as described in the comments above each array, and then paste them into the file.

I think this should have been obvious though?

I'm not too familiar with git, but have you tried doing 'git add ../firmware/target/arm/imx233/sansa-fuzeplus/powermgmt-fuzeplus.c'?  I think that message just means that you have modified a file but not added it to your commit.

also   the data    i dont know how to etermine wich ones are the proper percentages as  the  percents there are based on pre existing percentages   i want to determine the proper curve

I would just like to add that doing this for a 50mV deviation (which, is entirely expected and can be counted as a standard deviation) is largely useless.

You will not see any appreciable change from doing so.

Using PMs to annoy devs about bugs/patches is not a good way to have the issue looked at.

actually after a crap ton of trial and error  i figgured a curve that works for my device  its about 100 mv off of standard    it now actually charges to 100 percent instaid of 95
