Does this prove David Vizard's 128 lsa formula ?

Some people will want you to believe that D. Vizard 'invented' tight LSA cams & that they were never used in production engines. Not so.
The Morris Mini 850 engine came with a 230* cam [ adv duration ], 107.5 LSA. The low duration allowed for smooth idle etc. All of the BMC factory production cams were ground on 107.5 LSA.
Some factory high perf cams were ground on 102.5 LSA....
