Which players have had the best and worst platoon advantage since 1946?

Maybe someone has done this before but I wanted to do it myself.

I used Stathead to find all the right-handed batters who had 2,000+ PAs vs. right-handed pitchers and all the left-handed batters who 1,000+ PAs vs. left-handed pitchers from 1946-2021. There were 720 RHB and 257 LHB.

The table from the Stathead search shows how many PAs each guy had against the selected pitchers and their career total PAs. So then I calculated a percentage each batter had for the favorable handed pitchers (so, for example, what % did RHB have against LHP?).

There are four tables below that show the top and bottom 25 for both RHB and LHB.

I also uploaded two Excel files that have the percentage calculations for all the hitters in both groups that are also ranked.

I noticed at Baseball Reference player pages when you choose the "Advanced Stats" option and look at the "Situational Batting" table, they have a column labeled Ptn%. 

For Hank Aaron, it shows he had the platoon advantage 26.1% of the time in his career (but for some reason I came up with 27.65% using the data from my Stathead search) and that the league average was 52.2%. Willie Mays had similar numbers while Stan Musial had about 64% and Willie McCovey had about 75%. 

So it looks like LHB do much better hear. It also seems like for most guys the league average was around 50% during their careers. Only 2 RHB even reached 50% of their PAs vs. LHP for their careers while all the LHB faced RHP at least 60% of the time. For all of the LHB combined, they had the platoon advantage 72.3% of the time. For RHB it was just 30.1% of the time.
