i just checked the results for the Mongolian Baiti column against v5.4.1 
running on Windows 8, and made what changes were needed to the MB column 
(mainly in the first section).

i also added a note to clarify which version of Mongolian Baiti i used, 
and mentioning that v5.0.1 gives different results, and that those 
result may also vary depending on whether you use nirugu or zwj.

you can see the diff at 
https://github.com/r12a/r12a.github.io/commit/bdfc7a0566b9b8979843969dfbfc0b0364c8904b

earlier this morning, in a separate commit, i also put in place a 
workaround for the problem where the nirugu/zwj switch was failing in 
Internet Explorer. So that should now work.
