The reason your getting difffernet answers is that FAR 61.75 is only really for Private pilot flying and holding a type etc complicates things which 99% of people won't have been exposed to.
Your not going to get an answer in this forum as this is primarily for students and not for experienced pilots.
They cannot give more than a private because the law does not allow them to - have a look at :
FAR Part 61 Sec. 61.75 effective as of 10/20/2009
My interpretation is that you have to do a test for the ATP in the sim (with ATP written of course)
Honestly I suggest you call a FSDO or the FAA directly they are very helpful normally. Or contact an FAA sim operator.
