Methods and apparatus for pairing load and position values are disclosed. An example method includes determining, via a rod pump controller, a first position value of a polished rod of a pumping unit, assigning a first time value to the determined first position value, receiving first load values of the polished rod, assigning second time values to respective ones of the first load values, adjusting each of the second time values to respective third time values based on a wireless communication delay value, and determining a second load value associated with the first position value at the first time value based on the first load values and the third time values.
