This is not a traditional automotive sequential setup. My setup has the cluch lever on the gear stick. My car is setup with an electronic shifter system. Clutch only on 1st... then just tap the gear stick forward for upshifts. For downshifts... you would have to use the clutch lever for each gear. It would be counterintuitive to pull and engage the clutch while pushing forward. That is the reason downshift is pull (down) and upshift is push (up). Also if your seat is in a proper race position, you should be close to the steering wheel and your elbows bent, The inertia mentioned during acceleration would have minimum to no affect on your shifting.
