This page answers the questions covered by the article Your First 28 Days in Google Ads Are Three Clocks, Not a Launch Schedule on groas.com. The article is the full, canonical source.
Direct answer: According to groas, there is no 28-day launch schedule, only three overlapping mechanisms: query matching explores what keywords can buy, the bidder calibrates predictions against conversions seen, and late conversions backfill reports. The article follows a home services campaign spending $200 a day, eventually producing about four leads a day, with most jobs booking three to five days after the click, to show what each week's evidence can and cannot tell you. Mistaking one mechanism for another can lead to cutting a campaign for a CPA it never really had or rebuilding structure just as it begins to yield useful evidence.
According to groas, there is no fixed launch schedule for the first 2-4 weeks. The article states the weeks below describe its $200-a-day home services account, not a schedule every campaign must follow. All three mechanisms run at once, and what changes is which one most distorts the view.

According to groas, the Learning label describes a status in the interface, not the end of calibration. Ads keep serving while the label appears, and predictions continue to change after it disappears. Waiting for the label to clear is not the same as collecting enough conversions to judge a target.

According to groas, the duration people call the learning phase is not a universal 28-day timer. For its four-lead-a-day example account, by week four the Learning label may be gone and there should be enough counted conversions and backfilled bookings to ask whether the setup is working. If CPA remains 40% above target after that fuller read, the article states another week of waiting is not a diagnosis.

According to groas, recent CPA divides spend by a conversion count that may still be missing conversions, with a 24-to-48-hour processing delay plus longer delays for offline imports. The standard Conversions column attributes a conversion to its click date, so the most recent days can look weak until late bookings arrive. To see the gap, the article recommends putting Conversions (by conv. time) beside Conversions, then checking Tools > Measurement > Attribution > Path Metrics for the Day Analysis, noting a low-consideration account may record about 90% the same day while a higher-consideration account may record closer to 60%.

According to groas, on day one Google does not know which queries make money, so with broad and phrase match matching tests a spread of related auctions. Even exact match is tighter but still matches within its interpretation of intent and needs conversion data to distinguish a useful edge from an expensive one. That is why the example account might show 42 different queries across 60 clicks on day three, with fewer new queries by week three because matching has begun to concentrate around searches that produced signals.

The article recommends asking three questions before editing: does the edit change the queries being bought, does it change what the bidder is predicting, and does it change scale or presentation. Adding or removing keywords, ad groups or campaigns can change the traffic mix, while a new bid strategy or substantial change to the conversion goal changes the task given the bidder. Budget and target moves do not, by themselves, erase its history.
