For me the plan is IR(R), then EIR, then IR(A). I fully understand that for your daughter or someone else the plan can be different. The OP wanted to know whether it's worth to do IMCr/IR(R) and I provided my point of view.
I am sending my daughter off to do the EIR as soon as she finishes the PPL.
And as soon as there is a school offering the EIR course
