With the Shark, I can keep it in 3rd and not have to waste time short shifting to 4th and then right back down to 3rd again. Short shifting to 4th and taking the turn and uphill is not an option because it is STEEP, and would completely defeat my car due to its lack of power.
In the end, keeping it in 3rd, despite bring well past the power band, still yields in more mph by the time I have to start braking than just shifting to 4th and downshifting again. That extra 200rpm is so worth it.
