You also get 495 from any 4 digit number made of pairs for example 1919 and then deducting 1199 you get to 6174 in not time so I dont see any wonder on this!

The wonder I see is you swap this digits by starting with the higher number in front example 9191 -deducting 1199 and you end up with 6174:))))
