There are 2 setting choices when shooting to a CF card.
IIQ RAW L is default and lossless and is about 1/2 the processed TIFF file
IIQ RAW S is smaller, loses some data, and is about 1/3 processed TIFF

Since I don't acutally have a P20 here to Test, I'm left to my average Math Skills. Keep in mind there are variations in backs and camera body used.
Processed P20 (8 bit - channel) is 32 MB half that is 16 MB. 1/3 that is 11 MB
1 GB = 1,024 MB
IIQ RAW L = 32MB and IIQ RAW S = 16MB

Approximations are:
1024/16 = 64 files ...... 1024/11 = 93 files

Check my math... :lol:
