OG Second Cut Typical Yield Percentage????

I’ve got a customer interested in second cut OG and a lot of it. What kind of yield can one typically expect vs first cut - 30%, 50%, etc.

Only considering 2nd cut, not further cuttings to be on the conservative side of the numbers.

Techniques to jack-up 2nd cut yield? Obviously nitrogen after the first cut, but what about purposely cutting first cut as soon as the heads start emerging, gleaning that off the field early to give more time for a higher yielding 2nd cut. Any varieties of OG that delivers 2nd cut yield better than others?

Location - western mountains of VA.

Any sage advice appreciated.

Thanks,
Bill
