My money is on slow fired at 25 feet.
My best shooting was more than 10 years ago when my 25 yard groups firing 17 rounds from a G17/G34 would be in the 4" range.
I never could shoot 17 rounds in sub 4" groups and with old age, bad eyes and now trembling hands the groups get bigger each year.
Most of my shooting is not done at distance or slow fire.
We may never know if the target posted was shot at 25 yards.
