That's interesting Phil - almost exactly the opposite to my experience!
Basal tests on MDI were always followed by a general shift up or down (because that's all there was) but since being on a pump I've noticed quite how variable my requirements can be from one month to the next. Over the last month I've needed to massively hike up my basal through the morning, but cut it right back between 3 or 4pm and eve meal time. High in one place, hypo in another - and everything else remaining the same. Quite annoying actually as it has taken far longer to get things working reasonably again.
When basal testing I tend to grab a chunk of cheese if I'm struggling - I know strictly speaking it's not ideal as the fat will convert eventually - but it does so over such a long timescale, and I can usually ignore protein entirely so I seem to be able to get away with it.
