For those who are still interested, here is my third post in response to Zach. The final rabbit hole I explored is the relative scarcity of GBs and GB/WFs compared to CBs.
Comparing the average pop of CB and GB in the PSA pop report reveals the following: 28,179 CBs and 1055 GBs--a ratio of 1 GB for every 27 CBs. I surmise that this is probably conservative; i.e. collectors are more likely to send in a VG GB Kluttz that a VG CB Kluttz, resulting in a relative over-reporting of GBs.
From this point on, you can make you own assumption about the relative over-reporting of GBs.
So I made the assumption that the pops of Billy Martin may be more representative of the printed universe of 3rd Series. That is, collectors MAY BE just as likely to send in a VG CB Martin as a VG GB Martin. (I welcome other thoughts about this assumption.)
Martin CB-959 pop
Martin GB-19 pop
A ratio of about 50:1. One GB for every 50 CBs.
And from my original post, 1 GB/WF for every 9 GBs
So, my tentative hypothesis:
For every 500 3rd series CB, there are 9 GBs, and 1 GB/WF.
That's it. As always, I welcome feedback.
Bill
PS. If you think I am still too conservative, make your own assumption. Are GBs twice as scare as I postulate? Then for every 1000 CBs, there are 9 GBS, and 1 GB/WF.
