Those are the 2 years figures, which would break down to about 47 PIs
(1139/24) per month. From what I understand, the rate is now about
90 PIs per month, which means that it has significantly increased
during that period.
Did it increase gradually, or can you see a connection to the new
minimum usage PA policy?
We have made 312 PI assignments so far this year. That's approximately
59 assignments per month (assuming my maths is right :-)). The change to
the first allocation policy came in in November 2001, so that should be
reflected, so what, in the other figures.
