Fifty nine words put F first and R third, and the FOR opening takes more than a third of them.
O takes the second box in twenty one of the fifty nine, thirty six percent, and A takes fourteen. E, I and U take eight each, so the smaller branches are perfectly level with one another.
FORCE, FORGE, FORTH, FORTY and FORUM are the reachable words in the O branch, with FORDS, FORKS and FORMS behind them. It is the richest part of the page.
S ends eighteen of the fifty nine, thirty one percent, and Y another eleven. Between them they take twenty nine of the page, which is the biggest single cut available anywhere here.
The last box first, then the second. E leads the fourth box on only ten words, so that box spreads too thin to be worth a turn. FIRST and FORCE are the two strongest openings, both common and both testing different vowels.
FORCE tests the largest branch and FIRST tests a smaller one, but FIRST also covers S at the end, which eighteen words take.
Only in the last box, and FORDO and FORDS behave the same way. The O branch is full of pairs like that.
A unit of electrical capacitance. It sits in the A branch and is the only word here ending in AD.
