A more realistic extrapolation is that to shoot his average of 27%, he would need to go 21 for his next 100 attempts... or 21%, and that is much more realistic. Long story short, while he is definitely playing better right now, I'll hold off until season's end before announcing that we have seen the new Abrams.
I think a lot of Tracy's current percentage has to do with shot selection. I expect that alone will help his 3 point percentage.
