In some situations I suppose so. But so much stuff is multiple target transition and reacquire in short time frame that I would encourage people to not be in the habit of doing that.
Yesterday there were stages that 80-90% of the competitors were timing out on. It would be better I think for people to get that extra shot off rather than adjust magnification.
I wouldn’t advise changing magnification on a multiple target stage. Things I factor in:
Mirage (in my location, this has about the biggest impact on magnification)
Topography
Single or multi target
Stability of wobble zone
Recoil management
I try to be at the maximum power that allows me to:
Mitigate mirage
Find my targets
Maintain an acceptable sight picture
Account for all shots
Meaning:
Less mirage = higher power
Easy to find target = higher power
Single target = higher power
Smaller wobble = higher power
Ability to mitigate recoil better + confident my misses won’t be far off target to require a larger FOV = higher power
And down here, during the summer months, mirage dictates 99% of the time. If I can’t get over 12x without a lot of mirage, there’s no need to worry with the rest.
Same with any of those. The minute any of them restrict me to a certain power, the consideration is done.
