The ALL Performance Index

The Apex Launch League Performance Index captures true skill across events and fields. We can't all play together in every event so this index properly rates players — no matter who they're competing against.

<850

Unproven

Outpaced by the field, or a long layoff

850–1000

Developing

Building a record in real fields

1000–1150

Contender

Regularly top-third in a real field

1150–1300

Elite

Wins majors, anchors regional fields

1300+

Apex

Dominant against elite competition

Your rating changes after each event: New = Old + K × F × T × M × (Actual − Expected).

K is how far a rating can move at your experience level.·F weights the size and strength of the field.·T weights the event tier.·M rewards dominance (how far ahead you finished).·Actual is your performance against the field and the course, and Expected is what your rating predicted.

Event tier weighting

Local, regional, and national events all have different weight toward the rankings. You still get rewarded for dominating local and regional events but the real chance to separate from the field comes from dominance at the national level.

Course performance counts

We don't only factor in your performance against the field but we evaluate how difficult the course actually plays, too. There are many factors that weigh into performance and the difficulty of the course is one of them.

BUILDING FROM THE BASELINE

With a new league, everyone will start on the same footing with a 1000 ALL-PI rating. Early events will be important for building momentum but consistency will remain king for climbing the rankings.

Four independent tiers: Men's Apex (A), Men's Launch (B), Women's Apex (A), and Women's Launch (B). Players are rated against competitors in their own fields and tiers.

Only ALL Sanctioned events with a field of eight or more players affect the ALL Performance Index.

ALL Performance Index Rankings

Every activated league member and their current ALL-PI. Ratings move after each sanctioned event.

The 2027 rankings open with the first sanctioned event

The ALL Performance Index ranks every player on a national ladder inside their own tier and gender. From an eight-person local stop to a regional major to a premier national event, every result moves your ALL-PI. The formula is tuned so that performance in Florida can be compared directly to performance in Missouri, Colorado, or anywhere else — no matter which part of the country you play in.
