[developers] tsdb result file

[Bart Cramer]

Hi,

Stephen: it happened with cheap, either in -tsdbdump or in slave form,
both with GG and my own grammar.

Indeed. Variation is both between and within test items.

Another thing: lately I committed a fix for ticket 23:
https://pet.opendfki.de/ticket/23. It solves the incorrect output of
i-length when PET is used in -tsdbdump mode. Before, it was off by 1
compared to normal input of a test items file in the tsdb podium. If
you use this field in this setting, please check whether it gives
correct output to you.

Thanks,

Bart.
