In some cases, yes. Speed normally means less forgiving, but bow compainies are making huge strides in that department. Really fast flying arrows generally mean the archer has to have repeatable, and good, form. Any little thing done wrong will be amplified.
BUT, there is an aweful lot more that goes into that equation than speed alone. Arrow quality and proper spine are a major variable as well. I don't personally feel speed is as much a hinderance as it was say.....5 years ago.
I might agree with this completely if you had stated 15 years ago instead of 5,nothing has really changed in the last 5 years.Nothing substantial anyways.15 years ago,speed was achieved with hatchet cams and low braces.Nowadays,we have aggressive cams with high refex but for the most part,decent braces but imo,the high reflex offset that some.
The main thing that is a concern with speed is forgiveness,not just in the bow but in arrow flight.Extreme speeds usually mean light arrows which are much less forgiving to outside factors such as wind and deflections.They also require perfect form for broadhead flight.Torque will cause you nightmares in tuning a really fast setup.
