The phonics test is of no relevance to good readers. Reading fluency depends on being able to read all common words by sight, instantly, without decoding. That is the final aim of instruction by phonics too.
How children learn to read is immaterial, as long as they do. And however they learn to read, they will be using phonics for writing, although even for that phonics is of limited use in English, as u can see by taking a closer at the 100 most common words:
Tricky
He, of, the, to, was,
all, be, are, have, one, said, we, you, by, my, call, before, come, could, do, down, into, look, me, more, now, only, other, right, she, some, their, there, two, when, want, were, what, where, which, who, your.

been, here, see, came, made, make, I, like,
our, out, about,
new, over, old.
Spelling for consonants are mostly fairly regular, apart from consonant doubling (shoddy body, bubble trouble). Vowel spellings are pretty chaotic.
