In every single one, he was holding more like 8-10 cm from the top of the pole than 3. On a 5.20 pole, that would put his grip at 5.10 to 5.12m. Many of the clips and pictures I am talking about are from his prime in the early 90s.
Actually in practice Bubka used grip as high as 5.27m (to my knowledge), but he has found it difficult to perform consistently on such a high grip and he has abandoned further grip development, later Petrov though it to be one of the big mistakes.
I do not know if Steve Chappell made 5.30 poles for Bubka, but there are 5.30 poles and even longer you know.
And yes I have seen 6.40 jumps.
