Event Predictor

Build an event from scratch and watch the full chain assemble: the event rating from level, size, and difficulty, the calibration that takes your own rating off the scale, and the Raw Rpts that turn into your Event RFORCE. Every step shows its formula, your numbers inside it, and what the result means. This is a sandbox: you control every input, including the ones the season normally computes, so you can explore the scale, test scenarios, and work out what numbers you need to hit at an upcoming event.

Multi-division events split teams into divisions, each with its own qualification and elimination bracket, then a Grand Finals between the division winners. RFORCE scores these in two pools, your division and the tournament as a whole.

The event

Platform
Select a platform.
Event level
Select an event level to set the L coefficient.
Enter the number of teams attending (at least 1).
Enter the baseline field size (N0), a whole number of teams, at least 1.

Difficulty

The season reset nulls every rating, so difficulty starts at 1 and the rating inputs below are locked.
Enter the typical result this season (R-bar-0), greater than zero.
Teams at their first event carry no rating yet.
Enter the event average RFORCE across the rated teams.

Your team

A team with no rating yet is not part of the rated set, so there is nothing to remove in calibration.
Enter your team's RFORCE, or mark this as your team's first tournament.

Enter RANK Rpts directly. To turn a ranking score into RANK Rpts first, use the RANK Rpts Calculator.

Judge awards

Select the judged awards your team earned at this event.

This calculator takes your event’s field strength at face value. The published RFORCE Index only does that once a season’s events have been measured to genuinely differ from one another. Until they have, it treats every event as average and returns a difficulty of exactly 1.0000 no matter how strong the field was.

That is where the current season stands, so for a real 2025-2026 event the published system would return a difficulty of 1.0000 today. The baseline field size is yours to enter here as well; the Index derives it from the season’s own median field size.

Everything else is the published arithmetic, unchanged. Use this to explore how the pieces fit together, not to predict a rating that will appear on the site.

Result

Build the event on the left. As soon as the required inputs are complete, the full chain appears here step by step, from event size all the way to the Event RFORCE this event would be worth.

The chain ends at Event RFORCE, what one event is worth on its own. To turn a ranking score into the RANK Rpts you enter here, use the RANK Rpts Calculator.
