+Subject: [PATCH] Configurable farmland trample height
+
+This is _not_ in block height or an exact science.
+During my testing I found very inconsistent values
+for the fallDistance variable. Here are the results
+of those tests (https://imgur.com/BojltJF):
+
+Value set -> Actual fall distance needed to trample
+   1.0 -> 1.25
+   1.5 -> 1.75
+   2.0 -> 2.25
+   2.5 -> 2.87
+   3.0 -> 3.5
+   3.5 -> 4.25
+   4.0 -> 4.25
+   4.5 -> 5.0
+   5.0 -> 5.87
+   5.5 -> 5.87
+   6.0 -> 6.75
