Here are some numbers for a 2010 Mirage
370 TTAF and engine BB retail is 861,625
770 TTAF and engine BB retail is 790,625
425 TTAF and engine BB retail is 853,063
825 TTAF and engine BB retail is 787,343
210 TTAF and engine BB retail is 882,725
610 TTAF and engine BB retail is 821,425
For each 370, 425, and 210 I simply added 400 hours and that is where 770, 825, and 610 come from. Remember is are just adjusting for airframe and engine time. I have not added any value for any installed avionics.
