No, the straight data is data. Without a theorem or conclusion, it doesn't prove anything.
In any case, I can pretty much guess what we'll learn - the old 1e modules had much more monetary value, both in magic and in coin. I wouldn't be surprised if the amount were an order of magnitude larger. What's more, I don't think it particularly matters. In 1E, loads of gold didn't really do that much for you, since there was no built-in method of buying magic, etc. In 3E, gold=power on a much more widespread scale, and thus the amount of gold is something that needs to be strictly watched. Also, the large amount of gold given out in 1E modules is mitigated by the need to spend gold to train. IIRC, the amount was around Lvl to be gained x 1,000 gp. So a group of 8 9th level PC's heading to 10th level needed 80,000 gp just to gain the benefits of 10th level, whereas now, they can be dirt poor.
