What's the general consensus on how many miles you should drive before drawing a sample? I had fuel dilution in my last sample and had drove it just under 10 miles for a warm up, the oil had reached 180 ish and normal operating temp is around 188-197 this time of year. Could I have botched my own sample by not driving it long enough before taking the sample?

I'd be more concerned about how fuel dilution is being determined. Where are you sending your samples?
Polaris labs through amsoil, it's a 6.0 PSD and it's driving me nuts because I just replaced the injectors to hopefully fix the issue, my theory is it may be residual left over from up in the HPOP because it was less than before
I probably could but I'm on the second oil change so it should slowly start working it's way out. One thing I did notice is that when it initially started it showed 4.8% at 8k miles and had a viscosity number of a very low 10 almost a high 9. This time I was at 6k miles give or take and the dilution percentage was 3.8% and the oil was still holding viscosity at a 12.4 if I'm correct shouldn't the oil have been very close to the previous sample on viscosity with such a small difference in mileage and fuel percentages?
When I read the title of the thread, my first thought was to always give the lab a mid-stream sample.
I use a pump and pull it from the dipstick
