Only eleven words put S first and V third, and the SAV opening takes most of them.
A takes the second box in eight of the eleven, seventy three percent. E takes two and I takes one. That is the whole distribution, so the second box is almost decided before you begin.
SAVED, SAVER, SAVES, SAVOR, SAVOY, SAVIN and SAVEY all sit on one stem, and SAVVY joins them with a doubled V. Landing in that branch confirms three letters and leaves only the last two open.
They differ only in the last box and both are ordinary words, which makes them the one real ambiguity here. SIVER is the lone I entry and completes the page.
E fills the fourth box in seven of the eleven, sixty four percent, so testing it is close to wasted. R closes four words and Y another three.
SEVEN is the strongest opening despite the small branch. It tests the E second box directly, and a miss puts you in the SAV family where the ending decides everything.
SAVOR is the five letter form and the one on this list. The longer spelling does not fit the pattern.
A drain or gutter, a dialect term. It is the only word here with I in the second box, so guessing it either wins or clears one entry.
Yes, it doubles the V across the third and fourth boxes. It is the one word here that repeats a letter.
