I wouldn't worry about the differences...

You do the best you can do with the equipment and sitting you have available.

It is likely more important that you maintain the same configuration and location so that you have good relative data from day to day, month to month over the seasons that you can compare like type settings when the year rolls around.

Many "Official" sites are not what one would consider perfect sitting locations (like over concrete for example) but they are the same as they have been for years and are the record of that area.

You might find that the accuracy of your instrument isn't within the difference anyway.
