All replies to my OP seem to be the stuff that needs to be better understood from technical side instead of the "what I've always been told" side. I have known hunter / shooters with decades more experience than mine that put a great deal of stock in this data. My own experiences tend to not factor it into the equation as much as I have been led to believe. I appreciate the feedback. I have a new MagnaSpeed chrony which I think is a step up from my Pro Chrony, but velocity is my most useful function of the device. Its definitely more consistent and has yet to miss a shot and don't give a hoot bout sunny / overcast conditions. Thanks to all who contributed.
