Thanks. Yes — I noticed. Why I prefer original docs. (And even those don't necessarily always agree.)

The listing you indicated has some units missing also. The aircraft numbers for the training units appear to be authorized (hoped for?). These units had many different types and numbers, in at least one case well over 100 planes (No. 1 SFTS). Also no aircraft indicated for other training units, such as the Central Flying School, Seaplane training Flight, etc.
