Roy, I have experienced the same thing as you on many deer I have let go to 4.5 but there have been a few that jumped considerably after 3. Most deer that were 4 pts at 3 are 4 points at 4. They just have added some mass and maybe some height. They get targeted at 5.5 regardless.
I don't target anything that I feel is less than 4. I have eaten a lot of tag soup but does keep me supplied with deer meat. The deer that we have taken off our land in the past years that were 4.5 or older have scored from the high 100 and teens to high 140's. With this year's monster and a another that went 161 2/8(another incredible deer in my book), this year was an exceptional year for us and not the norm.:)
