This especially makes sense if your controller is nice to the batteries. I would guess if we brought the 0-60 times down and charge/discharge cycling range to 4

  >charge/discharge cycling range to 45-75% I assumed most EV's let you set this when you are charging or am I expecting too much?

    One anecdotal data point but Tesla does let you set a charge limit to enforce this buffer. As for a discharge limit it's just about being careful I suppose.

  Is the charge/discharge range really an issue? 45-75% vs. 10-90%. I'm not an expert but from what I've read seems hi-speed charging is more relevant regarding battery life.

    From some research I've done, charging to 90% vs 100% roughly doubles lifespan, 80% vs 90% doubles it again, and it has less and less impact below 80%. Discharging to 20% vs 0% doesn't seem to have as much of an impact, but still noticeable. So 20-80% or something like that is a good cycle range to use. Heat is also a big factor, well insulated batteries with active liquid cooling or similar should help a lot. With good insulation you can control the temperature of the batteries better on hot days because the ambient heat isn't warming them up as much. It's also useful in the winter to keep them warm. Battery thermals is something Tesla seems to realize is important at least, it seems like many other electric cars don't really do active thermals, and that results in hot batteries just from parking outside on a hot day.

      Nice! What sort of rig do you use to test battery cycling?
