Laura, I think you must have misunderstood Jan, she explained it
correctly, you probably just got confused with the wording. The MM
pumps deliver the basal in 0.1 unit increments. So your rate per hour
determines how frequently you get that 0.1 unit increment. If your
rate is 0.1/hour, you get one "infusion" or "bolus" of 0.1 unit during
that hour. If your rate is 0.2/hour, you get 2 infusions of 0.1, on
the half hour. If your rate is 0.3/hour, you get a basal infusion of
0.1 every 20 minutes.
I did fine on an MM, even during the night with 0.3/hour rates, and I
always assumed it didn't make any difference. But, when I started
using an Animas (which has the every-three-minutes infusion of basal),
I noticed how much easier it was for me to cover exercise by lowering
my basal. I think when I reduced my 0.4/hour rate to 0.2/hour on the
MM and then exercised, I did not have a constant enough supply for the
insulin needs of exercise, so would find myself sometimes going high.
This would not be a problem for those of you with a higher rate, nor
for those of you who can disconnect to exercise (something that would
have always made me go high). Also, suspending all basals is more
reliable for getting my bg up on the Animas (This can be useful if you
have realized you have to lower basal rates, something I spent the last
2 perimenopausal years often having to do. It can be even more useful
if gastroparesis has stopped you from digesting the food that you had
already bolused for.)
But I do miss being able to disconnect just after the click of a basal
increment and reconnect before the next one, and not miss any insulin.
Also, on the MM I could look at the day's history before I disconnected
and when I reconnected and be able to replace it exactly. With the
Animas, I have to approximate -- or else stay detached till I have
missed an amount that is an exact tenth <gr.>.

Bruce, a dosage of 0.1 every 10 minutes would be 0.6/hour. At any rate
other than 0.6/hour, it would not be delivered every 10 minutes. There
is something wrong with your info. I spent 4 years using an MM for
mostly lower rates than that.
