Tom Tango thought it would be a good exercise to run the data from the previous post for 20 year periods in the past. Here’s the list from players active in 1964:
| Batter | Age 24 Season | PA | HOF |
| Al Kaline | 1959 | 3776 | Yes |
| Vada Pinson | 1963 | 3552 | |
| Mickey Mantle | 1956 | 3491 | Yes |
| Orlando Cepeda | 1962 | 3220 | Yes |
| Bill Mazeroski | 1961 | 3174 | Yes |
| Hank Aaron | 1958 | 3173 | Yes |
| Frank Robinson | 1960 | 3155 | Yes |
| Eddie Mathews | 1956 | 3141 | Yes |
| Ron Santo | 1964 | 3089 | Yes |
| Tony Kubek | 1961 | 2900 | |
| Carl Yastrzemski | 1964 | 2676 | Yes |
| Zoilo Versalles | 1964 | 2661 | |
| Roberto Clemente | 1959 | 2560 | Yes |
| Johnny Callison | 1963 | 2426 | |

| Harvey Kuenn | 1955 | 2177 | |
| Dick McAuliffe | 1964 | 2171 | |
| Roy McMillan | 1954 | 2099 |
So 24 players in 1964 and reached their 24 season with at least 2000 PA. Thirteen of them made the Hall of Fame as a player. Note that pre draft, there was a baby bonus rule that required teams to keep high priced amateurs in the majors the first year they signed. That’s why Al Kaline didn’t play in the minors.
Here’s the table for 1984.

This group contains 25 players. Six were elected to the Hall of Fame, Albert Pujols is not yet eligible, while A-Rod, Bonds, and Sosa will not go in for PED use. So ten deserving out of 25.
Combing the results, we get 31 players elected to the hall, one who will go in on the first ballot, and four with asterisks. Let’s put Pujols in, so 32 out of 93 get elected, 34.4% and 38.7% if you include asterisks.
