Much
On the 24 up-days MS bought 730,836,476
On the 29 down-days they bought 1,252,046,633
53 days = 1,982,883,109
These numbers are not to be relied as I have used average results and (as LTI points out) MS have to follow a set of rules that will also affect the outcome.
Saying that there does appear to be a trend towards buying more on down days.
