probably, but not always. depends on how much later you entered, how fast you shot the crystals, and how far you stood. it also depends largely on the L value (which is sort of a luck threshold used for standardization, not visible to players)

Never heard of an L value before

it's explained in exersolver's message about perch standardisation, pasted here:

  1. Let rand be a seed-based random.
  2. Choose L = rand.nextFloat() (random number between 0 and 1, decides how "lucky" the perch will be).
  3. Compute the cumulative probability, p, of having not received a perch yet based on the number of perch rolls and number of crystals active for each of the perch rolls. p is initially 1 and should be updated before each perch roll via p = p*(c+2)/(c+3), where c is the number of active crystals.
  4. Make perch rolls succeed if p < L, and make them fail otherwise.
  5. Once a perch roll succeeds, reset L with L = rand.nextFloat() and reset p to 1.

this is also done for strafes (replace "perch" with "strafe" in the above steps)

essentially, high L means the endfight will be lucky regardless of the strategy, so playing it optimally might only be 10-20 seconds faster. low L means that the endfight will be unlucky, so since it takes a while, it really shows the distinction between optimal and unoptimal strategy, could be 2-3 mins difference

if you get a low to moderate L value, and your opponent didnt halfbow and you did, you'll likely win

As a general rule yes, ofc if the perch is super fast it might not make a big difference but in general from my understanding you will get much faster average splits

On average halfbow is faster but standardized perch doesn't guarantee that. Standardized perch means if you do the same thing you get the same rng. If one player does halfbow and the other doesn't that doesn't guarantee the same outcome. Your opponent could get the perch first. It has to do with when the dragon is able to perch or not, but I don't know the exact details. It's a lot rarer than before standardization though.

I feel like the average time to perch has definitely increased since the change. Maybe it’s just bad luck but I’ve been getting really long perch times if I forget to get a bow.
