I've been away from the forum for much too long, and I apologize that no one answered your question. Being that so much time has passed, this is likely no longer useful to you; however, I would still like to respond.
I suppose you are referring to the Daysim report which reads as, "Useful Daylight Illuminance (UDI): The percentage of the space with a UDI<100-2000lux larger than 50% is 73% for active occupant behavior." First of all, this uses a very outdated notion of UDI where autonomous was 100-2000 lx. The Daysim engine never updated this, but nowadays the thresholds are as follows:
Anyways, the actual results files in DIVA reflect these thresholds. You can use Excel pretty quickly to find the answers--see below.
