oil pressure and adjustable hydraulic valve adjustment

Lay out how you figured this, and what is your rocker ratio?

1 T would be 1/24" which is .042

1/2 T would then be 1/2 that or .021"

X whatever your rocker ratio, 1.5? would be .03'd something

3/4 of .042 is about .032, X 1.5 rocker is .047
