The films Bruce uses the most are:

Tri-X 320 asa rated at 160asa
Hp5 rated at 200
Tech Pan ? rating

Since he uses Tri-X for most of his work I would imagine the chart is most accurate for that film. But as I mentioned I have used it for APX 100 and FP4 with good results.

Nothing beats doing you own tests though. As they always say, your mileage may vary.
