I agree (this one will likely get moved to the Archery Section).
With todays technology you don't have to shoot big weight like we used to back in the days of aluminum arrows and heavy heads just to assure complete penetration at 20-30yds. I can remember when the average bow did well to get 200fps and 250fps was SMOKING. Now days kiddy bows can get that!
Just about any 65-80+% letoff, quality bow with 50-60#s, carbon arrows and good broadheads can shoot THRU any deer within 30-40yds. Honestly, any carbon arrow with a 100grn or lighter head doing in the 275-300fps range will allow you to use only 1 pin out to 30yds. (gonna be maybe 1.5"-2" high at 10yds and that much low at 30 but still "minute of kill zone")
Now days everyone thinks you HAVE to shoot 300-350fps to kill a deer. I guess if you are going to "stunt kill" like I've seen a few TV guys do and take deer at 60-75+yds then yeah you can't get one fast enough. But I personally think it's just unethical to attempt an arrow kill at such ranges, there's just SO many things that can cause problems (both man made AND natural) under such conditions.
