Hi,
I've recently found that - may it's bug or not, judge yourself - processing time given in "Show info" in Chunk is a value of the time from start to the end of the duration of the process but it's not "processing time" or "time of calculations" - because if you pause process for about 5 min ...then these 5min will be added to your processing time...
...just wanted to share this information with those who attach importance to this, and didn't know
