Have retested the Greater Than or Equal To operator usage and confirmed it works perfectly fine. I've tested this with integer field type, decimal field type, and text field containing an integer as well as text field containing a decimal. In all tests the condition worked fine. The condition is the only reason for the plan to keep renewing in this case for you it's constantly failing. I suggest switching to a decimal field type instead of a text field type since you need partial values. This would at least guarantee a safe value to compare against is returned.
