Thanks for the detailed report.

I have reproduced the problem. There is definitely a problem in the out
feature and in the internal calculation.

I hope I can provide a fix soon.

By the way. I have recently restructured the web presentation of tecomp.
In that process the hint to the mailing list has been lost. I have
invited you to the mailing list and will put the hint to the mailing
list back to the web pages in order to make it easier to give feedback
and report bugs.
