Doubling budget kept resetting learning. The 20% ramp fixed it

Every time I 2x'd a $500 ad set it dumped back into learning phase (Meta's recalibration where delivery gets unstable) and CPA spiked for 3 days.

The boring fix that actually held:
— Raised budget 20% every 48 hours, never more
— Only ramped on days CPA was UNDER target the day before
— Froze the ramp completely on any losing day

Took 9 days to crawl $500 to $1,180 — but it never re-entered learning. CPA stayed inside $30-34 the whole climb.

Risk: it's slow, and a slow ramp means you eat more days at lower volume. If you need scale THIS week, this isn't it. Try the 20% rule on your steadiest ad set.
