Enough detail to interrogate the comparison without turning the tool into a paper.
A permanent career ledger
We rescore each main-draw finish on one fixed 2026 scale across majors, Masters, ATP 500/250, Challengers and ITFs.
We count each result once and keep it for the rest of the player’s career. You can still choose Grand Slams only for a cleaner big-stage comparison.
Annual-maximum normalization
ATP points ÷ maximum countable base points that year
The denominator follows the rules and opportunity set, so a dominant contemporary rival cannot change it.
Known historical seams
1990s ATP totals included opponent-quality bonuses; 2020–22 used a temporary COVID retention window. We flag both periods and leave the official points untouched.
Full definitions, Brazilian benchmarks and sources
Brazil’s No. 2 is definition-dependent
Thomaz Bellucci owns the higher peak rank in this pair (No. 21). Fernando Meligeni reached a Roland Garros semifinal and an Olympic semifinal. Luiz Mattar’s seven tour titles make him a strong future addition when the historical point treatment expands.
