We apply a matrix interpretation of kind constructor based matrix interpretation (containing no more than 0 non-zero interpretation-entries in the diagonal of the component-wise maxima):

Following symbols are considered usable:

TcT has computed the following interpretation:

WeightGap {wgDimension = 1, wgDegree = 0, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
Proof:
The weightgap principle applies using the following constant growth matrix-interpretation:

Following rules are strictly oriented:

Further, it can be verified that all rules not oriented are covered by the weightgap condition.
