The only reason I asked was because our team has done a ton of testing in regards to different wheels and tread. Based on those results, 1.4 is a bit high, but I'm not going to split hairs over it. I was just curious as to where he got the number from as its been a point of interest for me and my team for a couple years now.
Safety margins are nice to include, but you do have to use them carefully. If you are adding a margin of safety into every variable involved in a design, you'll end up building something thats way overbuilt. Using one here is fine, but just make sure you are not also accounting for extra margin somewhere else and compounding your margin.
