310.15(B)(3)(A) has the following wording:
(4) Adjustment factors shall not apply to Type AC cable or to Type MC cable under the following conditions:

[R

a. The cables do not have an overall outer jacket

Elementary, I assume, but does this apply the group of several MC cable with individual jackets as long as that group does not have an overall jacket ?
 
IMO that relates to PVC coated cables like parking deck MC.

It certainly reads that a standard mc cable - without the jacket- does not have to do adjustment factors. :?

It says that if it meets all of those conditions you can use the 60% correction factor. If it does not then the standard 80%, 70%, 50% bundling rules apply.

Sometimes those dang trees get in the way of the forest....

One can concentrate too closely on the wording of one sentence...
