Cenedril Vestin

Data Collection for later use and speculations - would be nice, if somebody could confirm my theory about calculation
I'm leveling my Vestin Cenedril, but I already unlocked level 80 (rank 8) - so my data won't fit the above table. Here are the bonuses I get, so the data can be entered to the table later on, after we found out the bonuses for unlocking the ranks.
50/80: +4860/+810, 51/80: +4957.2/+826.2, 52/80: +5054.4/+842.4, 53/80: +5151.6/+858.6, 54/80: +5248.8/+874.8, 55/80: +5346/+891, 56/80: +5443.2/+907.2, 57/80: +5540.4/+923.4, 58/80: +5637.6/+939.6, 59/80: +5734.8/+955.8, 60/80: +5832/+972 ...... 70/80: +6804/+1134
There seems to be a formula bonus calculation:
:bonus = rankfactor * level
Rank	rankfactor
+magic attack	rankfactor
+ magical crit rate
