Question about Figuring out when shows aired

[OneBidTris]

I was watching a Season 1 episode on Youtube last night and looked at the pricing game calendar on Scorpz's site. When I saw what date it was there, it got me thinking, how do we know exactly what day these early shows aired? I'm guessing a majority of these early episodes on the page are GSN airings, so we don't have exact dates, just general ranges. But there are multiple lineups that repeat over the course of the month. Take August 15, 1973 for example:

Hi Lo
Five Price Tags
Double Prices

There's two other lineups from around that date where the same 3 games are played. How do we know that it's August 15 and not July 23 or August 29 of that year?

In that particular case, without going back to check, I'd imagine that either that episode was on the DVD set that released in 2008 or we were able to check the game results against Roger's records at some point.

It was not on the DVD set.

Tris, this thread should be of assistance to you. It lists all of the episode numbers and recording dates from August 1972 through July 1974.

However, sir, you've missed a key detail of Tris' question... that thread may detail the tape dates, but is of no use to disambiguate between two episodes with precisely identical lineups. In that case, Roger's records would have to be the source (that or some of the things Scott's shared over the years, such as in this thread).

Mea culpa.

I had run out of editing time, but would have added that in the case Tris listed, GSN lists a recording date of July 1973. Cross-referencing with the linked page and the Season 1 calendars removes the July 23 and August 29 episodes from being possibilities due to neither having been recorded in July 1973.

(Though I am well aware that GSN has indeed shown incorrect recording or airing graphics on other programs.)
