Profiler - Help Needed Interpreting Results - Same node appears multiple times

[Anonymous]

Hey guys Ive got a rig that became much slower on a recent version I produced (after adding a layer of follicles  on some input mesh , which drive joints driving a second skin/mesh)

To start figuring out exactly _why_ this was happening thought I'd profile it. But Im getting a bit confused as it goes deep, the same nodes seem to be computing multiple times? At a certain depth the follicles seem to each be getting hit twice, and each of them seems dependent on a unique evaluation of a deltaMush deformer.

I really hope Im just reading this wrong, can anyone shed some light? Ive attached a screenshot as well as the profile itself.

Thanks!
