I admit to not reading everything so this may have been covered. This is my opinion and may differ from everyone else's. I see pay in 3 categories, load pay, people pay and time pay.
Time pay covers things like detention and layover when the truck could be moving and generating load pay but it's not. The last time I checked (and every time prior to that) my hour was identical to the driver's hour. An hour of the truck sitting was an identical amount of time for them and for me. I split time pay 50/50 since we have the same length hours. In the future if time shifts so one side has a longer hour than the other I will adjust the 50/50 split.
People pay covers things like hand load/unload, inside delivery etc. and pays specifically for people doing things people do. If I happen to be at the same dock at the same time and participate in the people work then I'll split with the team 1/3 for me and 2/3 for them. Since that is highly unlikely and so far no longer has happened I pay 100% of people pay to the team.
On loads I follow the common 60/40 split giving the team 60% plus 100% of FSC. I also give 100% of DH pay because that is to partially offset the fuel cost of getting to a pickup. Since the team pays for the fuel they get the DH pay.
That hopefully gives at least some insight in one particular system.
