Congratulations on the reduction, and hi from BFG and me, not visited before
I can't even imagine shooting a full dose that low! I was telling DH about it this morning and he said 'Isn't that what we're hoping for though? Get him low and keep him low?'
The early part of this cycle likely played out just the same as it would have done because of the depot of the 1.25u so shooting the higher dose would not have likely played out differently, in Cameron's case with the data you have we can see that you've taken the dose up safely and taken reductions as they have come so it would have been ok to shoot the full dose, you'll get there.
One thing I wanted to point out was that this morning's amps seemed to be a falling number, to me that in itself was an indication that shenanigans could be underway, you did the right thing by getting a +1, which was about the same as amps, again another sign that the cycle was going to be act, so getting +2was a wise move, but you may want to consider a lc snack at +1 if a similar situation arises again, it could be enough just to keep him surfing those low greens when the insulin onsets instead of onset resulting in a drop below 50.
The point of TR is to try to keep them in the healthy range 50-80(human meter) for as long as possible sometimes holding on to a dose by actively steering the numbers with LC snacks is a successful way of doing this. If he really wants the reduction he will tell you.
This reduction to 1u is coming fairly close to the previous one, the 1.5u dose at only 4cycles might still have been a little in play here. So watch for this reduction holding if it seems like it's failing you may need to go back up to 1.25u, be guided by the numbers.
As you've shot a BCS, that will have also drained the depot, so that will need to stabilise too.
