Again, it is NOT weighted. Hits don't matter. TOTAL BASES do. Slugging percentage is NOT measuring hits. It is measuring how many total bases a player gets per at bat. Each base is weighted the same. Slugging Percentage is literally measuring how may bases a player gets, per at bat. HOW the player got those bases, DOES NOT MATTER. Thus, it is not a weighted average. It is literally TOTAL BASES/AT BATS.
I'm not denying that it is an average, but it is represented in percent form.
What it definitely is not, is a weighted average. The type of hit doesn't matter. Only the total bases matter.
30 singles is still just 30 bases. 10 triples is also 30 bases. Only the total number of bases a player gets is being measured. HOW he got those bases doesn't matter. Thus, the average is not weighted.
EDIT: I do see how some places do incorrectly attribute it to be a "weighted average" by saying that home runs have more weight than triples, triples more weight than doubles, etc. But, this is simply just not accurate. A home run is 4 total bases. A single is 1 total base. So, to figure out the slugging percentage (average) you take hits right out of the equation.
Example 10 At bats.
AB1=1 total base
AB2=2 bases
AB3=0 bases
AB4=0 bases
AB5=0 bases
AB6=4 bases
AB7=0 bases
AB8=1 base
AB9=0 bases
AB10=1 base
10 at bats. 9 total bases.
SLG pct.= .900
the average is not weighted. It is literally the number of bases the player got, divided by the number of at bats.

(1B + 2Bx2 + 3Bx3 + HRx4)/AB that is the formula for slugging literally from mlb,
https://www.mlb.com/glossary/standar...ing-percentage
Why is this important? It is showing from their own page that each hit you get an AB IS weighted. If you look at as you are and say did the AB get 1,2,3, or 4 bases then technically you are correct but how you get that is based on what kind of hit you got. This is why it is considered weighted when you do the math.
The only reason you knew how to find out how many plates some hitter got was by doing the math. You knew a home run was worth 4 plates and a single was worth 1 plate. If you didn’t know the math to know that you must multiply each hit by their weighted total of plates then you could have never found the total plates they got.
This is simply how Mlb has said the formula works, they say that you look at it as each hit is worth x points ie plates and then you add them up. This is why it is seen as weighted in that instance.
If we rewrite the formula then yes we can just say how many plates did you get per AB and that will in some ways take out the wording, but by definition you can’t get 2 plates without hitting one double. So in the realm of calculations that double impacted the slugging average making it higher than if it has been a single.
