27-30 sets per week per muscle group: too much?

Just realizing that I'm doing about 3 or 4 different exercises per muscle group every day that I work, and I go to the gym 5 days/week, alternating push & pull days.

So that translates to 27-30 sets per week per muscle group. Is this too much?

Am I calculating this right? I assume decline press, incline press, fly would all be considered the same muscle group, so those would add up to 27 set per week.

I don't want to overwork things and def don't need to spend time doing junk reps.
