No, it's a fair question.
Constant Volume Bars are meant to take time out of the equation and evaluate price action based on units traded. However, visualizing it this way does throw out the time element completely, and there's no need to throw out that information. With time-based bars, seeing a high volume bar means something. Similarly with constant volume bars, my thesis is that whether it happens quick or slow is also useful. It's just reorganizing that information. I actually like to see time and CVB side by side.
