The first split is from march 5 - march 10, then there is a 3 day break (for review), then the second split is from march 18-20. The workload is correct at 9 days.
In Resource Planning, however, the workload is 1 for every day in that span, including march 13-15, which should have no workload according to the splits:
Since some of the time during a task duration is actual work (the bid) and some of it is waiting on reviews to come back, the idea is to more accurate define an artist’s workload during that time.
Another thing you could consider is whether or not it might work to customize the Workload calculation to better suit your needs, as described on Help.
For example, maybe you have some other field on your Task entity besides duration which more accurately captures the amount of “true” work to do or maybe it would work to use a calculation that basically says “the workload is duration x 0.8 because artists typically spend 20% of the task duration waiting for reviews” or if you are using time logs you could do something like “the workload is the bid minus time already logged.”
I would recommend using timelogs if you are expecting to do anything usefull with bid info in SG.
You could set up pages/views that tell you exactly which shot/asset/person you need to check in with because the time logged is over the bid time or close to.
