Home PSA Set Registry Forum

I'm writing a program to analyze the pop report. Suggestions?

Partly because I'm a geek and partly because I think the pop report is hard to read onscreen, I'm developing a little software program (written in PERL, for you fellow geeks) that will help me analyze it a little better.

The main focus of what I want to do is to compare pop reports of a specific set between different dates to see what's changed and what hasn't. This data could be used to graph what cards seem to be increasing in population (and at what grades) versus stagnant cards. You draw your own conclusions as to why you're seeing what you're seeing. Basically what I'll do is save the pop report from time to time (hit SAVE-AS from the browser) so I'll have an archival "snap-shots" of the state of the report at different dates.

Anyway, I'm looking for suggestions as to what other features I might be able to add to help analyze the report. Specifically, what can I do with just a single pop-report file to draw any useful conclusions?

Thanks,

John

    How about this (as an example)

    During the month of June 200X, 1,000 cards from X set were graded -- and of those, the following grades were assigned:
    3 PSA 9, 298 PSA 8, 504 PSA 7, 165 PSA 6, 30 qualified cards....

    I've kept similar data for selected subjects from the Pop report over the last 3 years or so. Very interesting to see the changes, when they happen, and which dealers get the 10s. (when they end up on Ebay...)

    And to think that this data was once only available in that huge book!

    I am actively buying MIKE SCHMIDT gem mint baseball cards. Also looking for any 19th century cabinets of Philadephia Nationals. Please PM with additional details.

    mikeschmidt,

    This is something I can easily add. One of the first lines in the pop report shows the current totals for each grade. This can also be done for individual cards, which is especially helpful when only one or two cards in a set are the most active, such as the '86 Fleer Jordan.

    I've been a busy bee today!

    Here is a summary analysis of the 1971 Topps population report between yesterday (7/25) and today (7/26) as of mid-day. The analysis for the entire set took roughly 20 seconds. Further style refinements are pending, but it seems to work!
