Grammar help "a RMA" or "an RMA"?

[Shawn <shawn -at- cohodata -dot- com>]

Greetings all,

I am experimenting with ProWriting Aid (see this review:
http://robinbneal.com/2014/03/23/robo-grader-review-prowritingaid-google-add-on/).
When you are a one-person tech doc team, even a mediocre tool like this is
pretty useful for proofing.

While running a grammar check, it pointed out the following sentence:
"...10 business days after receipt of a RMA number."
and suggested that I write this as "an RMA".

I understand that if a word begins with a vowel... but I don't think it
does. However, for the sake of curiosity, I decided to do a Google search
for ["a RMA" or "an RMA"].What I found was absolutely no consistency. Even
within a single document, both "a" and "an" were used. :-O

I am inclined to consistently use "a RMA", throughout my document.

Can anyone offer some advice?

Thanks
