I went back and checked the precipitation analysis plugin and it seems to be working correctly on the "total" section, but appears to be incorrect on the "balance" tab. I was not able to get the balance to work correctly on the plugin or the block.
Okay. I figured this out on my own. Yea! There is no problem with the block. The issue was in the main setup. It asks you to enter the normal rainfall values. I did enter them, but I set the measurement as mm and not inches. I changed it to in. and the block is working correctly. Once more it was user setup error.
