Ah, I believe that might be due to a field modifier in the calculation. Part of PDGA's round rating calculation takes into account how the rest of your field performed. It is nothing withjn our ci trol, ratings are all done by the PDGA

I got this from Gemini:
In the PDGA ratings system, a round rating is not a "fixed" value for a course; it is a statistical calculation based on the specific group of players (called propagators) who played that layout at that specific time.
If you see different ratings for the same score on the same layout between FPO and MA60, it is usually due to one of the following three reasons:
### 1. Different "Propagator Pools" (Unofficial Ratings)
This is the most common reason you see a difference while a tournament is still live. How it works: Unofficial ratings are calculated separately for each "pool" of players. If the FPO field has a high concentration of high-rated players (propagators) who all struggle on a specific windy morning, the system thinks the course is playing "harder." The Result: If the MA60 pool plays the same layout later that day when the wind dies down and they score better relative to their ratings, their "unofficial" ratings for the same score will be lower than the FPO players'.
### 2. Significant Weather Splits
If a tournament is large enough that divisions play at different times (e.g., FPO in the morning and MA60 in the afternoon), and the weather changes significantly, the PDGA will often separate them into different Official Rating groups. Example: If a morning fog or heavy rain makes the course significantly more difficult for the FPO field, but it clears up for the MA60 field, the PDGA software will recognize that the "Scratch Scoring Average" (SSA) for the morning was higher. Therefore, a 60 in the rain gets a higher rating than a 60 in the sun.
### 3. The "Official" Reconciliation
It’s important to note that Unofficial ratings often change once the tournament is finalized. When the PDGA office processes the final report, they usually combine all players who played the same layout into a single large pool to create a more accurate "Official" rating. If the FPO and MA60 ratings are different right now*, check back after the next monthly ratings update. In most cases (unless there was a massive weather difference), the PDGA will normalize them so that a 60 = a 60 across both divisions.

### Summary Table
| Situation | Will the ratings be different? | Why? |
| :--- | :--- | :--- |
| Live/Unofficial | Yes (Often) | Calculated using only the specific players in that division's current pool. |
| Official (Standard) | No | PDGA combines all players on that layout into one "Super Pool." |
| Extreme Weather | Yes (Official) | PDGA manually splits the pools so players aren't penalized for bad luck with the wind. |
Would you like me to look up the specific tournament results you're viewing to see if there was a reported weather split or a layout naming error?

The "Why" Behind Differences: If the same score on the same layout in the same tournament results in different ratings, it is usually because the tournament director set them up as two separate layouts in the system, or the rounds were played in significantly different conditions (e.g., calm morning vs. windy afternoon).
Jenny Umstead Mar 29Layout-Specific, Not Division-Specific: Ratings are calculated based on the scores of all "propagators" (rated players) who played the exact same course layout in the same round.
