Just curious...what is the point of paralleling 4 microphone elements?

I wanted a desk mic to go along with my KX3 station. Wanted something
more portable than the Heil boom and mic I use on my other radio. I
have experimented with dynamic mics on the KX3 and didn't get the
results I liked but did get very nice results with using 4 CUI
electret condenser mic elements in parallel. I used the CUI
CMA-4544PF-W from Digikey and used a small project circuit board to
physically arrange them in a 2 x 2 config. Then I trimmed up the board.
For the mic body I found a unused Shure 522 on ebay (some company had
them for a conference table system and had a great price). The 522
has an adjustable neck height and a PTT (with lock). I gutted the
body and fitted the new electret element assembly as well as used a
3' TRRS patch cable that I cut 1 end off for the mic cable, it also
had 90 deg ends.
I am pleased with the physical results as well as very good audio
reports I am receiving from the regulars that know my signal, still
not to the level of my FTDX5000MP but getting better with each tweak
and DSP update (using 1.32 which has made a noticeable improvement).
I am using a healthy level of compression and mic gain that shows a
solid 5 bars.
