I’ve always assumed that P1, P2 and P3 are constituent programs of the L3 suite – Bakery Valuations.
From reading some of the files, these are very complicated programs and the machine was tiny.
The following shows the amount of time involved.
From looking at Lenaerts Notebook No 8 page 39 written on Monday, Dec 3rd 1951, he refers to the P programme’s successful run on Friday afternoon (November 30th) at 2:20. Note that Len then continues with his usual pre-occupation (faults!).
Note also that on the 28th, page 37, he notes the successful completion of P1, suggesting that perhaps P2 ran on the 29th.
Three days therefore looks a reasonable view.
