Anyone else encountered the capped oversubscription of a 130% on a SRP on a VMAX3 yet?

Rather frustrating that you could oversubscribed on the VMAX1/2 pass a conservative 130%

Confirmed with EMC first level and local EMC contact(s). Still awaiting a Technical explanation which I might be able to digest but it appears the only fix is to throw more di$k at it.
