Talipes Calcaneovalgus (TCV) severity scale

There is a Pirani scale that is standardised for talipes equinovarus (TEV) and you can use this for both severe positional and structural talipes but is there anything similar for Talipes Calcaneovalgus (TCV)? Maybe the degree of resting dorsiflexion, the passive planarflexion range, heel involvement/degree if eversion, medial joint prominence?
Any help will be appreciated :)
