The issue I think you were asking about is when the sigma is paired with the D500, in af-c when every other shot is out of focus... have you found this to be true for your lens?

If you are asking me whether "every other shot is out of focus" then the answer is no.  I sometimes see this type of behaviour if I have the 2x converter (TC-2001) attached (so the lens is then a 1000mm F8 combo) but I don't have any problem with the lens without converter or the lens with just the 1.4 converter (TC-1401).   I probably get typically about 90 to 95% in-focus success rate with the bare lens and similar with the TC-1401 attached provided the light is reasonably good.  With the 2x converter the AF performance is not as good - but that is to be expected as the D500 AF is pushed to about it's limits with an F8 lens.
