2 different PS allocations in the same plan

[Santo Gold]

A PS plan has 2 different PS allocations. One gives a flat percentage to all eligible participants. The other one allocates on a service & comp weighted basis. The same group of participants share in each allocation. Would 410(b) be tested separately for each of these allocations, or can we combine and test together in 1 410b test?

Thanks

Combine.
