Hey @jkool702 - I've reviewed your changes - here's some feedback:
Overall Comments:
- Consider breaking down the complex pLOADA_new calculation into multiple steps for better readability and maintainability
- The debug print to stderr should be guarded by a debug/verbose flag rather than always enabled
Here's what I looked at during the review
- 🟢 General issues: all looks good
- 🟢 Security: all looks good
- 🟢 Testing: all looks good
- 🟢 Complexity: all looks good
- 🟢 Documentation: all looks good
