Treat each quad like an asset and each shortcut like a high‑volatility trade. First map out the critical path and assign a probability of delay to every segment, then set a tolerance threshold. Use a small buffer at the end of each milestone and monitor the variance; if it exceeds the threshold you pause and reassess. In practice that means working through the mesh in controlled batches, reviewing each quad for errors before moving on, and only taking a shortcut when the projected benefit outweighs the risk of cascading defects. That keeps the schedule on track while keeping the risk profile low.

You’re right, a 0.1% slip can flip the whole quad. I’ll keep the buffer tight, audit each batch, and avoid any half‑measures. Discipline on the geometry and on the numbers keeps the risk in check.
