Bart -

I sent you more data, password Kurt2 and Kurt2.1
I had no trouble downloading the Kurt1 data from your site. This data was
with no toroid. Is it possible the data came from my computer? I have found
with moderm PC's and giga bite hard drives that nothing put on the drive
ever leaves the drive even when deleted.

Hi John -

Cool. I'd like to run the numbers. You mentioned Kurt1 in Java. I haven't
seen it come through if you
sent it from JavaTC (hope I don't still have a problem there? I have
received quite a few the past
couple weeks and the email-out function seems to be working). If it made it
to your email, maybe you
could forward it to my email.

Also, the column heading "Java (Acmi?)" is only JavaTC, not Acmi. I'll run
Acmi numbers from Acmi for
the coil once I get the data and put those numbers into the mix.

Take care,
Bart
