@klintE - flight path by Indonesian MoT

Interesting graphic based I suppose on radar data published by Ministry of
Transportation. In Indonesian...
When I put the numbers in and try to translate the text I get this (all dots are 'spaces' to get the layout right):

.ft/min....ft......ds..ssec..dft...estfpm.....description
..1400..32000...6...6...xxxx....+1400......6 seconds after the maneuver to the left, QZ8501 suddenly pitched up/climbed
..6000..33700..15..21..1700...+6800.....15 seconds later, the aircraft had climbed 1700 feet from its original level
11100..36700..13..34..3000..+13846....13 seconds thereafter the aircraft reaches its maximum altitude
xxxxx..35200...6...40..1500...-15000......6 seconds thereafter It had dropped 1500 feet
xxxxx..27300...x....xx..7900...-xxxxx......? seconds, the aircraft continued to descend and dropped another 7900 feet
xxxxx..xxxxxx..x....xx..xxxxx..-xxxxx......? seconds, shortly after touching heights
xxxxx..xxxxxx..x....xx..xxxxx..-xxxxx......? seconds, and finally radar contact is lost

With ft/min = as indicated in the image, ft = as indicated flight level, ds = time step in seconds, ssec = sum of time steps which gives a timeline, dftestfpm = fpm based in numbers stated (they differ from the fpm stated, note also the 13k versus 11k and the 15k), description = indonesian text after my rough translation.

The climb of +13846 fpm is 1.98 times the value of pprune mentioned 'recoverable' incidents of 6000-7000 fpm.
..The drop of -15000 fpm is 1.58 times the value mentioned in the AF447 recorded drop of 9500 fpm.

Wonder what you gents think of that?
