Lol no worries Howard - I’m not worked up at all. The topic of bearings and bearing life interest me greatly - I’ve actually studied this topic extensively.
With respect to my SLC - I believe the C4 hubs will do me just fine, it’s a 99% street car and whatever track miles it may see will be at 6/10th, if that.
Bearings have a very non-linear life; keep load forces below a certain point and you have infinite life. As you creep into the danger zone any incremental increase in loading results in an exponential decrease in life. Additionally if you damage your bearings then bring loads back down, you’re still hosed - even a microscopic area of damage on the raceway will lead to accelerated damage despite low loads.
