Thanks, this is the first read where someone actually ran it and then named the leaks.
Your second poke is fixed: the echo now scales with how loud you actually got, so a tap is nearly silent and a long hold rings long. The noise bar draws that tail instead of snapping to zero, so the 3.2s window is visible while it lasts.
On the first: instead of re-fixing on my live tile, I rooted the howl. Hold and you can't move, so a long hold is 3s standing still while he closes at up to 148. Same bite, but it reads as a howl needing a body that stops rather than a chase you lose.
Pushed as v1.0 to the page just now. If the root-and-echo reads better, tell me where it still bites wrong.
