This is not my idea of relating to the " average and inexperienced shooters" :
" Serious competitors and ethical hunters will either have 2 bows ready for the 2 jobs, or 2 sights for their bow, one zeroed in with the broadheads and another zeroed in for the fieldpoints."
I' ll answer the question about " temperature, lighting, natural elements, and distance. Temperature affects different material by way of what is termed CTE. This means that plastic will expand differently than aluminum and teflon will also be different, etc. If a hunter has a sight that is made of any of the multitude of modern ' plastic' materials available today, and many sights like Trophy Ridge do, then you' ll have this sight moving at a different rate than your riser. The proportional difference and how it would truly affect its relation to the rest would have to be determined.
A tournament shooter like Mr. Ragsdale can adjust his sight before the tournament starts. This is standard practice. A hunter, however, gets only one shot and he/she better make it count. Therefore, a hunter must adjust things to the " middle of the road" , as PW so eloquently put it.
Lighting can definitely have an effect on sighting a bow. The natural elements I eluded to include the wind and rain. I think I discussed how distance to the animal should be kept to a minimum.
I' m sorry that you look at my posts as spin. The spin I see is when nonrelevent material is brought into the picture.
Do whatever you want. It really has no affect on me or many others in this life. Most here just want to gather as much information as possible and relate it to their situation/application.
Good shooting to all; no matter how you choose to tune.
