# Scorebug Win Probability Orientation Bug
## Project
major-domo / discord-app-v2
## File
`services/scorebug_service.py`
## Google Sheets Layout
The scorecard outputs:
- **C8** (`all_data[6][1]`): winning team's abbreviation
- **D8**: that team's win probability percentage
## Problem
Code was treating D8 as always the **home team's** win%, regardless of which team C8 named. This produced an inverted win probability whenever the away team was winning.
## Fix
Read C8 and compare to the home team abbreviation (from `game_state[4][1]`).
```python
winning_team_abbr = all_data[6][1] # C8
home_team_abbr = game_state[4][1]
win_percentage = float(d8_value)
if winning_team_abbr != home_team_abbr:
win_percentage = 100 - win_percentage # flip to home team's perspective
```
`ScorebugData.win_percentage` is always stored from the **home team's perspective**.
## Key Takeaway
When consuming a spreadsheet that outputs "winning team + that team's probability," always check orientation and normalize to a consistent perspective before storing.
