If you watch others shoot for awhile (3D, various types of practice shots, even hunting or tutorial vids, etc.) you're likely to see that what they 'think' they do for form isn't quite what they actually do, lol.
Most good hunters, for instance, will use a variety of different stances/draws based on the situation, even if they don't realize it at the time. And this makes sense. Shooting with only one static/never-changing straight arm, or straight up, or swing-it-up approach is not only impractical, it's pretty self-limiting and self-defeating in the real world.
As for the term 'swing draw'. I believe it is as missed-used as the terms 'traditional' and 'instinctive'. VERY few people use a full-blown swing draw (from thigh to eye level draw) when shooting, it's simply not needed or not practical for most situations. Most folks that 'swing draw' have the bow up (off the thigh) about a third to halfway to start, with a bent bow arm. It promotes focus on the target rather than the bow, better rhythm once the draw starts and still manages to produce limited movement ...a very effective combination overall. Straight-arm drawing, although having a little less movement to start with, is more restrictive regarding how much bow weight can be handled safely (beware those shoulder/elbow problems) and can actually result in MORE movement if the shooter needs to let down before taking the shot (the elbow rotates outwards more on letdown, more so than with semi-swing arm). So, I think that comparing what is better, swing or straight drawing, really isn't an apples-to-apples thing. There are just too many variables between theory and what folks actually do. If I were to guess how most folks usually draw my guess would be a semi-swing arm...because it makes the most overall sense.
As far as how well the terms 'traditional' and 'instinctive' work today, well I'll just say they're an archery version of Rodney Dangerfield and I'll leave it at that, lol.
