Just eight words put O first and R third, and no two of them share a second letter. There is no pattern to lean on here, only a short list.
Eight different letters appear in the second box across eight words, so every one of them is unique in that slot. A guess aimed there eliminates a single word.
The fourth box behaves differently. Only three letters appear there, with E and I taking six of the eight between them, so that is the box worth testing.
OGRES is the one word here most people know. OARED and OKRAS are the next most reachable. ORRIS is one of two in the group that repeat a letter.
With eight words the arithmetic changes. Reading the whole list costs less than a guess, and most of these you would not produce from memory.
Percentages are close to meaningless at this size. S ends three words, which sounds like a trend until you notice it is three out of eight.
It is the only one most people would produce unprompted. OARED and OKRAS are real but rarely reached for.
No. OUNCE runs O, U, N, C, E, so its third letter is N rather than R. It belongs to the O first and N third list instead.
O is an uncommon opening letter to begin with, and requiring R in the third box narrows it to almost nothing.
