This study compares several timing techniques against the turning points people report from their own lives. The dates are supplied without consulting a chart, and the astrological years are scored before those answers are opened.
Can a chart identify the years that divide a life into before and after?

Methodology
A method can succeed at one part of the problem and fail at another, so convergence, precision and personalization are evaluated and reported on their own terms.
01
Convergence
When several distinct timing techniques agree, are reported turning points ranked more highly? This tests whether overlapping signals carry more predictive information than any one technique alone.
Techniques examined
Secondary progressions
Solar arc directions
Outer-planet transits
Solar and lunar returns
Eclipses and annual profections
02
Precision
When a technique flags a turning point, how closely does its predicted period match the reported date? A broad indication and a precise forecast are not treated as the same result.
Resolution
Year: the primary level of analysis
Season or month, where the data supports it
Date uncertainty built into the analysis rather than treated as exact
03
Personalization
Does the real birth chart perform better than plausible incorrect charts? This tests whether correct birth data adds information beyond general age patterns or common cycles.
The comparisons
The participant’s real chart
Matched sham charts scored by the same rules
Age and recency as a non-astrological baseline
Why this is measurable: Convergence has a dated pre-registration, locked on July 21, 2026, before participant charts were scored. Its formula, weights, candidate-year denominator and holdout rules were frozen in advance.
The questionnaire
What You’ll Be Asked
Answer from your life as you remember it, not from what your chart or a previous reading says should be true.
01
List at least five events that substantially changed the direction of your life.
02
Give the year for each event, adding the month and day only when you remember them confidently.
03
Choose the single event that created the clearest before and after, and optionally add comparatively quiet years.
The findings
Results in Three Phases
The analysis becomes more precise as the sample grows. Every phase keeps the misses.
Phase 1 Now filling
Preliminary
A first look at the signal once 400 charts are in. Early results, wide uncertainty, published openly.
Phase 2
Expanded
The analysis runs again at 2,500 charts, with tighter estimates and checks on what survived Phase 1.
Phase 3
Full
The complete analysis at 5,000 charts, including what worked, what failed and what remains uncertain.
How it stays honest
How We Keep It Honest
Blind first. The chart is calculated and its convergence years are recorded before anyone reads the participant’s answers.
Misses published. The findings include where these techniques fail. That is part of the reason for running the study.
