Can't find a way to compare your graphs to the report.
It seems that the only plot that gels with the graph is the CAS, transformed into m/s and with an intent to plot a continuity below 40 kt (~20m/s).
Furthermore, the pitch vs path are, IMO, quite impossible as they suggest a negative AoA value between your time plots ~83 to 102, which are not supported by your AoA computations and do not match the reported values.
(Pitch - AoA = ~ Path angle )
As for the acceleration values, I'd only take the report time checks of 25:45:15 and 15:45:23 when the CAS went from 98 to 144 kt, hence an acceleration of 23.66m/s over 8 s, or just under 3 m/s/s or .3g against your .4 . That would be nit-picking if it were not for your graphs after your 100 time plots : positive longitudinal acceleration (over .5G at one time) while the airplane is again going through the second stall.
Sorry, I don't buy it.
Maybe your reference zeros should be re-worked.
But nice attempt, nevertheless...I don't have the courage to even start what you did.
