Infill Wells Canadian County, OK

Could you help me with the question above. It would be very unusual for a mineral owner’s share to come out an even .01 on a Division Order. It is my thought, the original lease would need to disclose the terms of the lease, 1/8, 3/16, 1/5 etc. Our latest lease offer is higher yet with a much lower lease payment. Help me, (us) understand how the terms of the lease, and the decimal share on the Division Order is in play. Again, never heard of a straight .01 on a Division Order. We record in each well or lateral each month on a mineral log. Those records go back to the 1950’a on perhaps 50 different wells over the years. I have never kept track of the decimal equivilant of the owners share of production, as there is no way (that I know of) of checking the accuracy of this number. Can it be done? Thank you for your wonderful answers that make complicated issues seem understandable. It is appreciated more than you can imagine.
