I'm still playing, but at 1:1:100 and 20 degs C with agitation for 60 s then 10s per 2 mins:
APX100 (trial ISO 80) (120 in small tank)- 13 mins (printed on G3.5 VC) so 16-18 mins should be good
Tmax100 (trial iso of 64) (5x4 in combitank)- 14 mins (printed on G2.5-3VC).
Efke 100 seems to take forever.........I'm up to 15 mins constant agitation 1.5:1.5:100. Prints a normal scene on G3 ish VC.

As far as under rating goes, that means I need to shoot and meter for what I'm rating it as, right? I should know this, but my brain is tired today.
Anybody with experience in TMAX (100 and 400)? That's all I can seem to get around here, unfortunately. Must start ordering Ilford from the net.
the massive dev chart says:
TMax 100 Dilution: stock EI 64 9 min temp 27C/80.6F
TMax 400 Dilution: stock EI 400 10 min temp 27C/80.6F
that 80 degrees freaks me out a little...seems hot. i'm only used to HC-110b at 68degrees, though.

yup thats right.
if you dont have time/ inclination to test etc, alter as you go on. If your shadows are blocked up lower teh film speed, if your highlights are blown out shroten your dev time, or vice versa, too falt - lengthen dev time .....
BArry thornton had a good article on testing for personal film sppeds and dev times on his website, but it's gone offline now ... did anyone copy it?
I've done 100 TMAX 5x4 in combitank at 20 degs C agitation for 1 minute then 10 seconds per minute for 14 mins. Fine for G2.5 VC print with colour head.

The site's been archived - not all of it is available but a fair amount remains.

When I use Pyrocat for 120 TRI-X, I shoot at ASA 400 and develop for 25 minutes with 1:1:150 dilution at 70F and agitate once every 5 minutes for 5 seconds. I can get full film speed that way. The results are very good for enlarging with a condenser enlarger for N processing on Grade 2 fiber paper.
thanks for that richard.
