A fair Tennis head-to-head holds the format, the era, and the count of 4 major titles constant. This Tennis guide keeps 1968 Open Era as the worked example and 4 major titles as the count held still, and it names ITF because the public frame reaches back to 1877.
1968 Open Era is the shared setting and ITF is the rule-maker since 1877. The comparison page should not mix a different sample into the same sentence. Say that figure out loud, then open the era control or the linked section on purpose. This is a reading of the Tennis atlas, not a bet, not a prediction, and not an official ITF ranking.

Start with "The format both names share". For Tennis, the concrete case is 1968 Open Era, and the count you hold still is 4 major titles. ITF is the body named here; 1877 is the reference year, so you are reading a published frame rather than inventing a rank.
The next check is "The era both names share". Keep 1968 Open Era in view while 4 major titles stays the unit, because mixing a different count would make the Tennis comparison look sharper than it is. ITF has been the public frame since 1877.
Pause on "The stat the comparison refuses to mix" before you treat every prize as the same kind of fact. 1968 Open Era is the example, 4 major titles is the count, and ITF does not ask this atlas to publish an official Tennis order. The reference year is 1877.
Close the loop with "Where to open the head-to-head". After you can say 1968 Open Era and 4 major titles out loud, open the linked Tennis section. The anchors remain ITF and 1877. This page still does not forecast a result.
This page shows how to read the Tennis comparison around 1968. It is not an official ITF ranking, not a prediction, and not a betting note.
