Flying over the Shino landscape

This big (maybe a foot tall), two-part vase came out of the firing late last week, glazed in layered Shinos that made it look a bit like the landscape of an alien planet. In the past six months or so I have been pouring Shino over Shino on many of my pots. Usually the base is a carbon-trap Shino attributed to Malcolm Davis, then a Bright Shino is poured over, then perhaps my regular ash celadon glaze. No order, not much forethought. Where the glazes overlap, they usually crawl unpredictably. Sometimes I'll pour ash glaze over the crackling Shinos as a way of blanketing them and keeping them from wildly crawling off the pot. The ash fills the gaps in the crawling and crackling Shinos and sometimes pools in the centers of the individual crackles. ... If any of that makes sense.
These glazes in this firing were newly mixed. I know that some pottery teachers and texts say we should always test our new batches before trusting them to our pots, but ... well ... I don't. I don't necessarily want the new bucket of glaze to look exactly like the last bucket. Consistent inconsistency is what I'm looking for, at least with these combinations.
