I've tracked these numbers in February, March, April and now July. Here is what I've found.
In seven weeks from February to April 328 cards were added to these counts. That's about 47 per week.
In 12 weeks from April until early July 1,444 cards were added - over 120 per week.
What years saw big increases? 1970 saw an increase of 335 cards (23.2% of the total increase), 1970 FB added 225 cards (15.6%), 1971 added 160 (11.1%), 1973 added 103 (7.1%) and 1981 added 100 (6.9%).
That all seems okay until looking at the changes in 9s and 10s graded. Of the 1,444 cards added during this time 76% of them are 9s or 10s. People submitting these certainly know what they are doing and can evaluate cards quite well.
What does this mean? Does anyone know how to determine who submitted these cards. I think I have an idea as to how this jump has occurred.
