Is there a more accurate way of determining slot port length with end correction for a subwoofer enclosure than the method explained by JL Audio in the link below? It seems that their method is just a ball park way of doing it but I would prefer a more precise method. The enclosure will be pretty big, made of 1.5" MDF, and I hate working with MDF because the dust gets everywhere so I don't want to have to remake the enclosure.

The Enclosure specs will be 2.5 cu.ft. net volume, 3"x13" slot port, tuned to 32Hz, 3 shared walls on port.
According to the tuning formula shown in the JL link above and solving for Lv this port should be 35.87" long. How can I determine what the end correction is and how the end correction will affect it?
Also, will flaring both ends of the slot port with a 1.5" round over bit affect its length similar to how the flare on a round port affects its length?
