NB: The following has fast data with 10 samples-per-frame rather than the actual number of 20 just to make the table smaller.

This is a solution to Spider slow jitter which happens by only writing slow data on slow frame boundaries. (i.e. whenever mx % FAST_PER_SLOW = FAST_PER_SLOW - 1, write the latest slow data that you have. As before, green cells are fake data; red cells are repeated data. We also have to detect instances where the above condition is never true during a slow frame and add data to keep slow and fast data aligned. This solution can result in discarded data (if the above condition hold multiple times in a single slow frame).

Lag slow data fix.
