Most definately thiers, of course.
Point is, i hated the daily activity planners and material lists and i now find myself doing at least the material lists for box store and auto part runs for stuff around the house. Its much more rare that i get home and have to go back... these were kinda certain builder specific (huge) jobs like comm highrises, data centers, water treatment ect.
The stretching obv. cuts down on minor injuries but the daily planners were implemented for insurance, liability and warranty info which bugged me. Helps because we can now see who screwed up all the blue phones or the deck work or such on anything...that works for our favor. If a accident and say a dirty test turns up, then per contract- if its a intel or gov'ment deal, then the g.c. can look at EVERYTHING that particular bonehead had his hands in, to be scrutinized.
I felt the need to explain the pro's and cons of the system. It works.
Also helps if its a cookie cutter job like hospitals or schools because in theory one has accsesss to a material list/guessed/actual time for say, the gym lights or backup gen rough in.
Helps w/material orders as well...
Ok, their time, our time. Who knows. It would be included or payed for- one way or another...
