Last I checked (I haven't watched the 10:00 AM run in some time), both airings are somewhere in the second season. The noon run is in between the 6th and 7th tournaments (they just aired the Vicki Lawrence storms off the set week), while the 10:00 AM run was about a tournament behind.
GSN was running the third season before Labor Day, when they switched to the second season, and it's been years since they've run the first season.
Last I checked, the 10:30 AM $25K run should be in early 1987, while the 12:30 run is in August 1986, having aired the 1000th episode complete with cake, and Dick making an unfortunate comment about Vicki Lawrence's outfit, very recently.
