The abbreviations seem to be French. I would guess the V is verticale and the H horizontale. The first four positions are the verticals and they are, in order, B for bas (down), G for gauche (left), H for haut (up) and D for droite (right). The last two positions are the horizontals, bas (down) and haut (up). The last two sets of numbers are DEL for delta (the difference between highest value and lowest) and MOY for moyenne (the mean or average).
All of which is useless unless we know which part of the watch is up or down, although the crown would be the likely reference point for the verticals. You'd need to ask the people who tested your watch. By the way, your assumption that the watch will gain in the crystal up and down positions isn't borne out by the numbers. There's quite a difference between the two.
The timegrapher is a pain for the fussy consumer. It shows up apparent flaws when the watch runs well enough on the wrist. I expect you're happy enough with this watch's performance, OP.
