WeightGap {wgDimension = 1, wgDegree = 1, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}

The weightgap principle applies using the following nonconstant growth matrix-interpretation:
We apply a matrix interpretation of kind constructor based matrix interpretation:
The following argument positions are considered usable:
uargs(a__add) = {1},
uargs(a__and) = {1},
uargs(a__first) = {1,2},
uargs(a__if) = {1}

TcT has computed the following interpretation:

Following rules are (at-least) weakly oriented:

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