There is no need for all these sets! Do you only do squats? Or do you do squats + other quad exercises?
Just do a few warm ups and save your energy and strength for your heavy weight. If you want to do a killer routine, do the opposite of what you are doing now. And NO NEED for all these sets.
Example:
Since you are doing 190 x 8 for your last set, you could do that weight first when you have more energy, and since that would be your first work set you will be stronger and more energetic and should be able to squat about 225 for around 8 - 12 reps.
SET #1 225 x 10
SET #1 225 x 8
Do this long set with only the rest it takes you to unload the weight.
SET #3
225 x 6
185 x ?
135 x ?
Your 3rd set is 3 different weights, as many reps as you can do. The time it takes you to unload the weight is ONLY how long you will rest in between weights. Try to be as quick as possibal. These are called descending sets AKA drop sets. These are killer and my favorite intensity to use.
You don't need to drop the weight 2 times, or you could add to 3 or more. I personally think 1 heavy set plus 2 drops (2 total sets) are perfect. If you do drop after drop after drop, etc you can overtrain big time. Be careful. When you add intensity to your lifts, you can do way less and get BIG results.
Also, another thing you could do on your non drop sets are rest pause sets.
Do your regular set then rack the weight. Take 10 - 15 deep breaths and bang out as many more reps as you can. Rack the weight again, 10 - 15 more deep breathes and bang out some more reps. DONE
Its not how many sets you do, its how you do the sets that counts. If you are blasting your muscles in just two sets, there is no need for 3 or more sets, of anything! AND no need for a lot of total sets for each muscle group!
CMON BUDDY.
