      Thanks @Sue, and well spotted!   I already discovered the flaw shortly after I had already posted – and subsequently edited my post, viz:

      “Follow up: I have just piloted this on my son and immediately realised that – in the numbers 4 and 5, where adverbs are employed – both ‘slowly’ and ‘exactly’ could equally be placed in alternative positions. So, my question now would be whether there is a way of accepting both alternatives in cases like these? Although, I would be more inclined to rephrase the original sentences to avoid this distraction. (I just added the adverbs originally to create a modicum of variety and interest.)

      All in all, I don’t think the activity really works in any optimum kind of way. Maybe a case of me following the tech rather than the tech addressing my intentions?”
