Hi Kag,
I don't know what you operate, but most of my previous types have large doors which open to let the gear transit, then close around the extended gear. Hence 3 limiting speeds with the gear: 1) Extended, 2) Lowering, 3) Raising.
What's yours?
That one:

“Positive rate” (Altimeter increasing)
I agree with your post, just one thing (again) "positive rate" refers to the VSI, "positive climb" to the altimeter.
The VSI gives a rate (positive or not), the altimeter a climb or a descent.
I know this is a detail, please don' t be offended.
