Expectation: everything is packed, settled, and working exactly as planned.
Reality: the garage-night decision has other ideas. Consistent preparation and written baselines make track decisions safer, faster to diagnose, and easier to repeat.
A little patience, a quick check to begin with a measured baseline, and a willingness to laugh at the timing usually restore order. The story gets better once the problem is behind you.
Garage nights always have a way of changing the plan! Having a measured baseline makes it much easier to spot what actually changed instead of guessing. Definitely worth the extra few minutes.
