David --

I'm very pleased to hear that you're getting good results by using the BTZS test information we've distributed. I'm sorry I don't have a file for HP5 that includes 0.3 Gbar data but I'll send you (as a separate email attachment) a PDF G/Dev chart for HP5 in D-76+1 that comes close enough to 0.3 to allow for reasonably sensible extrapolation. It puts the developing time between 3 and 4 minutes which is practical and safe with the tubes if you follow our suggested instructions for using them.

Do you have the WinPlotter program? If you do I can send you the file so you can run it yourself for other conditions of use. If you don't have the software but would like to try it, there's a demo version available for download. Go to btzs.org/Software/Plotter for Windows. Then click on Plotter for Windows and near the end of the text you'll see the demo version link. The documentation and instructions are also available for download.
