John, this is entirely in line with my predictions then, since you loaded the equivalent of 4 x 10 files of composer/panel/sound etc and 6 full custom style groups which are roughly the equivalent of at least another 6 x 10 performance type loads, and generally quite a bit more.

If the card is half full, then the equivalent for the full 8 MB is around 20 x 10 performance type loads, or in the region of 200 performance files or more.

If you add in sequences with typically single songs this may tend to bring the total down to the 150 performance loads region. It all depends on the subfile combinations you are saving, and how efficiently you arrange your work.
