this year I have had two Y to J and one J to F -- which based on number of flights is higher percentage than last year.

I find it quite interesting that this some Golds expect the upgrade the majority of the time. Many flights wil lbe overbooked when you check in but with no shows etc (they are quite good in revenue management to work out thenumber of no shows) flights go out right on or woith limited empty in Y or J depending. I am sure there is a thread where someone with inside information informed us of th epercentage of no shows on some routes.
