How to read this

Days to stockout at scale is the only date that matters once you turn spend up. Judge it against your restock lead time, not against how comfortable your warehouse looks.

When that gap is negative the campaign kills itself. You spend to build demand, run dry, lose the momentum you paid for, and restart the learning phase the week new stock lands.

Weeks of cover above 26 is the opposite problem. That is capital parked in a warehouse instead of buying inventory that actually moves.

Sell-through tells you how much of the total pool you cleared in 30 days. Under 20% on a product you are about to scale is a warning, not a green light.

What to do with this number

Running dry mid scale costs more than the stock you did not buy.

Spend gets pulled, the momentum you paid for dies, and the learning phase restarts the week new inventory lands. We build the scale plan around your restock window so the budget and the supply chain move at the same speed. Book a call and we will pace it against your real lead time.
