Sixty one words start with RI, and the fourth box is an E in nearly half of them.
C, S and V each take the third box in seven words, with F, L and N on five apiece. Sixteen letters appear there, so the third box divides the page into small pieces rather than useful branches.
RIGHT, RIGID, RIVER, RIDGE and RINSE are the entries a puzzle is most likely to want, with RIFLE, RIPEN and RIVAL close behind.
E fills the fourth box in twenty eight of the sixty one, forty six percent, which is the single most reliable fact here. RIDER, RIDES, RIMED and RIPES all run through it.
S closes twenty one of the sixty one, thirty four percent, with Y and R on eight each. Only four words repeat a letter, seven percent, so a visible double narrows this page sharply.
It is the most common word here and its GH shape appears on almost nothing else on the page, so a miss is very informative.
It is the strongest assumption available at forty six percent. RIGHT and RIGID are the notable words that break it.
A small channel or groove. It is one of the narrower entries and not one you would guess.
