Bowling Pins With GURPS

My best run, round 4, was a whopping 6 seconds.

That's six turns in GURPS.

Let's look at the givens.

The range was 5 yards; -2 to hit.

They're smaller than a torso and skinny; let's say -7 to hit.

All-Out Attack (Determined); +1.

No risk to self; +1.

No risk to others; +1.

Moderately well lit indoor range; +3.

-3 to skill in the first round.

We add an additional +3 for later rounds because now the range and speed are known (determined by seeing what missed and what hit).

-0 to skill for rounds 2 through 4.

Of course, we have no idea what my Guns/TL8 (Pistol) is.

And we don't know if a hit that knocked a pin over, but left it on the table is a function of damage or a missed hit.  It could be represented as a miss by one, or it could be just a crappy damage roll.

Let's call knocked over a miss by one.

In round one I fired 9 shots, two misses and two missed by ones.  Five of the shots were slow enough that I should get the +2 for the pistol's Acc (first shot and last four).

Timer goes off and I aim for 1 second.
Shot 1: Skill -1, hit.
Shot 2: Skill -3, miss by 1.
Shot 3: Skill -3, miss.
Shot 4: Skill -3, miss by 1.
Shot 5: Skill -3, miss.
I slow down start aiming between shots.
Shot 6: Skill -1, hit.
Shot 7: Skill -1, hit.
Shot 8: Skill -1, hit.
Shot 9: Skill -1, hit.

In round 2 I fired 6 shots 8 seconds.

Again I aim before my first shot.
Shot 1: Skill +2, hit.
Shot 2: Skill +0, miss by one.
Shot 3: Skill +0, hit.
Shot 4: Skill +0, hit.
Shot 5: Skill +0, hit.
I pause to aim.
Shot 6: Skill +2, hit.

Rounds 3 and 4 are about identical.  5 shots, 6 seconds.

I aim before my first shot.
Shot 1: Skill +2, hit.
Shot 2: Skill +0, hit.
Shot 3: Skill +0, hit.
Shot 4: Skill +0, hit.
Shot 5: Skill +0, hit.

What are the probabilities and statistics?  Hey, FuzzyGeff!  You're good with stats!

I have 25 shots fired.  No misses at from 4 at +2 to hit.  One miss by one and 11 hits at +0 to hit.  5 hits at -1 to hit and two misses by 1 and two misses with a -3 to hit.

Update:

If we count the knocked down, but not off as bad damage rolls, my Guns/TL8 (Pistol) skill is 15.

Now I wonder what my DX is!

  1. I'm intrigued by the question of miss by one or crappy damage. That's the thing to think about.
    I'm inclined to say damage because you're not transferring enough force into the pin to push it off the table.
    But honestly equally valid is that you're not striking the correct zone, miss by one, to knock it off the table.

    1. It's a tough nut because the variable of damage is dependent on the precise location of the hit.

      So a bit off the sweet spot and it falls over instead of being knocked off the table.

      But there's a couple instances in the rules where a miss by one still scores a hit, but not in the desired location...
