Re: Srt gear ratio
Reminds me of the story of the IBM repairman back in the dark ages who comes out to fix a mainframe.
Dissapears inside, they hear a "clank" and all the lights come on and tape (9 track) reels start whirring and he comes out holding a small hammer.
Presents a bill for $ 5,000.00. Bean counter says he needs an itemized bill so the guy with the hammer writes down:
Hammer strike: $5.00
Knowing where to strike hammer:: $4,995.00
