130 five letter words start with SI, and no third letter takes more than about one in eight.
N leads at about twelve percent, R at eleven and L at ten. T takes eight, M six and C five.
SINCE, SITES, SIGNS, SIZES and SIDES are the most common entries, and each one sits on a different third letter.
SIGHT, SIXTH, SILLY and SIXTY follow them, so the group holds a reasonable stock of ordinary words.
SIXTH and SIXTY both put an X in the third box, which appears in almost nothing else on the page. An X anywhere settles the answer to one of those two.
SINCE is the most common entry and a reasonable opener, though SIDES tests a wider spread of endings if you would rather keep options open.
They differ in the last box alone, so landing either one settles the other immediately.
Its G and H appear together in little else here, so confirming either one narrows the group faster than a common letter would.
A noticeable share, clustered on the M and N branches. Treat the count as generous rather than as a list of playable options.
