Well observed.

Incidentally, in the above I see the word "got" a couple times, which I think may be some typography accident / anomaly? -- I read:

<< This sonnet arrangement Is often referred to as got the English sonnet or got the Shakespearean sonnet . . . >>

Of course some poets (methinks including Shakespeare, but would need to check) will vary the strict iamb somewhat in practice -- so rather than just 2 syllables, there may be occasional clusters of (e.g.) 3 syllables, but still keeping the 5 beats & overall the iambic rhythm (despite variations).
