Right wrist bend

[bobbyj]

I am unsure about the detail of the bent right wrist and how to find the best amount at impact fix. The questions below highlight my confusion:-

1.Is the constant bent right wrist ONLY to ensure a constant flat left wrist (i.e coincidental)?
2.Which is first, ball location or right wrist bend?
3.Can you have too much right wrist bend? Can it lead to an arched left wrist?
4.Is the optimum amount of bend for each club just found with trial and error?

I would be glad if anyone could clear some fog on these points.

Thank you in advance.
