Computer Check-up Test Results on 2012 Plug-In

I've made an offer on a 2012 Plug-In with about 30k miles (46k km) on it.

I had an auto testing firm with good computer checking capabilities do a check over for me, with emphasis on battery. They tester said everything looks apart from a gash in one of the tyres. Not sure how to interpret the print-outs. For example, voltages are given for eight battery blocks . . . here are the min and max readings

Batt block max vol 25.86 V
Batt block min vol 25.67 V

From my minimal knowledge these are good numbers because the difference between blocks is quite small. No? Are the numbers good?
Or on compression

Engine speed of cyl #1 871 Rpm
Engine speed of cyl #2 866 Rpm
Engine speed of cyl #3 866 Rpm
Engine speed of cyl #4 870 Rpm

It seems unreasonable to post all results here. Question is, where can I find numbers for basic test parameters, including listing of healthy ranges?
