That's what I was getting at: The requirement is initial MEP (6 hours) and SEIR>MEIR (2hours+3sim) - You basically need 8 hours in a place. If they're offering you 50% off that then take it - that's a great deal!
Of course the BIG question is why do you want an MEP rating if you don't intend to fly an MEP? That really makes no sense. You already hold an ATPL - why not just convert that to an ATPL by taking an LST in a 737 and forget about flying pistons?
