The hidden line
Plot each cut against its number of steps and the six points fall on a straight line. Follow the line back to zero steps and it lands on 27.03 seconds: the base the table is built from, printed nowhere on it.
Each step is about 4.7% of that base. That is why the same idea works for every age and event: a different base, the same recipe. The Cut Card on this site finds the line for any table you type in.
The line under the table
Another table sits on the same kind of line. Its AAAA cut (one step out) is 31.29 and its AA cut (three steps out) is 34.09. Where is its base?
