[G12] [Fwd: [g13] Ratio of results files to original data]

[Gagik Gavalian]

Hi All,

I'm currently working on a different DST standard (other than BOS or 
ROOT), with compression ! And this conversation got me curious.
0.05% seems extreme for all the information stored !
Can you guys be more specific what information is stored in this DSTs ? 
because the reduction I get from BOS files is only about 50%.
But when I compare, I compare the information stored only in HEAD,TAGR, 
and PART banks.

I assume Daria meant the whole BOS file with all the banks in it, am I 
right ?
