I've been poking around in regards to this.
They haven't fixed it yet by any means, as they are still missing data but mostly in the micros as far as I can see.
But then I decided to look into some of the other sites that track cash poker (market edge, poker edge) and they have the same basic holes in their data.
This means one of two things (or both).
1. The sites all buy their data from the same tracker.
2. FTP did something that broke ALL the tracking providers.
Now I get why the sites like HUD users. This has caused a rake bonanza for online poker rooms. But HH tracking sites are not the same. They have changed the face of online poker, but it is NOT in the poker room's favor this time. Ask anyone who plays low to mid stakes HU tables.
I sure hope FTP can keep making it hard for PTR et all. And I hope Poker Stars
