Of course you would personally notice. But the parent was talking about the effect on muscles. And it has been long estsblished that 5-30 reps (perhaps even highter) will cause the same hypertrophy. Obviously, for practical reasons the optimal range for each exercise will vary. For squat 5-10 is definitely better than 10-20 let alone 20-30. For DB side raises highter reps would feel better than the lower rep range.
