A 1877 rule change in Tennis breaks a straight line from earlier seasons to later ones. This Tennis guide keeps 1877 first championship as the worked example and 1 major titles as the count held still, and it names AELTC because the public frame reaches back to 1877.
Before and after 1877 first championship, the figure 1 major titles may not mean the same thing. Footnote the break, name AELTC, and keep 1877 as the year the older frame began. 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 AELTC ranking.

Start with "The season before the change". For Tennis, the concrete case is 1877 first championship, and the count you hold still is 1 major titles. AELTC 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 season after the change". Keep 1877 first championship in view while 1 major titles stays the unit, because mixing a different count would make the Tennis comparison look sharper than it is. AELTC has been the public frame since 1877.
Pause on "The figure that is no longer comparable" before you treat every prize as the same kind of fact. 1877 first championship is the example, 1 major titles is the count, and AELTC does not ask this atlas to publish an official Tennis order. The reference year is 1877.
Close the loop with "How to footnote the break". After you can say 1877 first championship and 1 major titles out loud, open the linked Tennis section. The anchors remain AELTC and 1877. This page still does not forecast a result.
This page shows how to read the Tennis comparison around 1877. It is not an official AELTC ranking, not a prediction, and not a betting note.
