Quoted from Lamberger:
I know 8 people with a TBL that aren't on pinside so that puts it at 140. 80 games were released before the new production started. Should be 15 EA's just from that alone, and that's just what I know about..I could be wrong.
I don't know whether DP is meeting their promised 3 to 1 ratio. But your calculations don't align at all with what DP has actually promised over the past 12 months. DP never said that ratio would apply to the ~50 previously produced games that were “resold” before the new production started -- quite the opposite, nothing from the sale of those games went to the EAs, which made the sale controversial at the time. And before new production started up, DP publicly announced that it would not be making any EA games at first, and that all funds for an undefined initial period would go to cover startup costs. DP shipped out the first EA game in mid May 2020, and that's also when it announced that it would implement the 3 to 1 ratio going forward.
So assuming DP has kept its word, 1/4 of all games produced since May should have gone to EAs. If you assume they were making 4 games/2 weeks over that period -- I believe that number came from DP but not sure if it was aspirational or a report on actual production numbers -- then they should have shipped roughly 34 games total: 17 new sales at $12.5k and 8 or 9 EA games. Again, I don't know whether that's actually happened, but at least it's based on what DP said they planned to do.
