Anyone else use the sneaking symbol?

[GreatGonzales]

Yeah I use the sneaking icon. My understanding that the duration of the sneaking icon also depends on the time the person took between taking actions. So if I move a runner up, see something that requires my thought, think about my next move in light of this information, and then take another action, the sneaking icon will last longer than if I took two actions in quick succession. Understanding this, I think, is key in misleading your opponent.
