OP it's great that you have a passion project but if I can offer some feedback.

• What are you trying to convey here? It's not clear. Acreage of a field that in most of the cases (based on your footnote) is arbitrary and tells me nothing.
• A quick verification of some of your wacky field shapes, and the photos in your post history, reveal that perhaps you've been too literal with your HR boundaries.
• Google Maps is an aggregator of several sources of imagery and isn't a reliable source for this type of work. I suggest using the RIGIS satellite imagery which is higher resolution and consistent.
