Efficient Progress and Rhythm Control

Acceleration framework:

• Economic rolling: maintain investment–return positive feedback, avoid cashflow breaks;
• Advance key points: complete core spots and control systems before high pressure;
• Wave prediction: observe–probe–reinforce loop, build before pressure arrives as much as possible.

Practice essentials:

• Before each wave, ask: which single upgrade now most increases survival chance?
• Keep a small flexible budget for emergencies;
• Do not chase "extreme times"—prioritize stability.
