Did a compression test (NE) aspect. The top 50ish cms didnt react. We had a reaction on the persistent slab problem approx 80cm on the first hit from shoulder. The deep persistent slab reacted on the second hit from the shoulder, approx 120cm. See images for reference you can see the 3 layers. In the bulletin avalanche canada states that a slide higher may step down, I think our test today supports that given they reacted within 1 hit.
