What is it with wing chun forums?! It doesn't matter what site, wing chun threads always have some stupid keyboard warriors trying to look smart online or trying to correct someone or bring someone else down with their "superior knowledge". Word of advice: don't try to run a mental marathon with someone if you're only a sprinter.
Now, I can't believe I'm about to have to teach grown men the definition of a word they should have learned in middle school...you should NOT have to be looking around the "web" either to know the definition of such a word. However, so that you keyboard intellects have something to look at, I'll retain a source for you as well.
First...wikipedia is not a valid source as colleges will not allow it to be used as a source for any paper. That site was meant to be a source of all knowledge--a mecca of human intellect; but mostly it's just people like those on these forums that spout off something they've heard in an effort to look intelligent. Referencing the second response, the definitions that were listed from the other sites are used for a different context of the word, as there are many variations to its definition.
PRAGMATIC in this context means being concerned with results...period. I'm now going to connect the dots for you, so pay attention.
Pragmatic: (this is the pertinant definition) "Of or pertaining to a
practical point of view or
practical considerations.
Practical: "consisting of, involving, or
resulting from
practice or action:
a practical application of a rule" or "mindful of the
results,
usefulness, advantages or disadvantages, etc.,
of action or procedure".

real book):

Simply put: In practicing a style or technique or theory of any martial art, the practicioner needs to be mindful of the results. Meaning that if you practice a particular movement or technique or theory, it needs to be practical enough to actually work in a combat environment. How will you know if it's practical? By consistent pressure testing to benchmark your training results.
In general, most of the folks that I've met that only practice one style, either don't pressure test, or they only do so against their own stylists. This does not create an effective fighter in my opinion because the exposure is limited. Cross trainers allow for a broader exposure to the elements that are out there, thereby improving their skills (assuming they are training properly) and their chances at successfully defending themselves or overcoming their opponent.
