Ok, so I tried to include some pretty charts and graphs to give a visual of where we are through Week 20 on our single pin conversions. If you think of anything additional you would like to see, let me know and I'll try and put it together.
First up is our single pin conversion rate by week. I have this data in table format on the link above but the chart shows our week over week conversion rate in visual form. I used the first 12 weeks to create our benchmark conversion rate (mean), shown on the right side of the graph at 76.51%. Under normal statistical guidelines, 8 data points above or below an established mean constitute a process shift. As of Week 20 we have four points below our established mean; four more points below the mean and we have a fucking negative process shift.
I for one am practicing twice this week to cut down on this HORSESHIT! My conversion rate has been shit lately and it shows in my scoring and in the chart above.
Next up is a pareto chart showing the breakout of single pin leaves. A pareto chart plays on the 80/20 rule, meaning you would expect 80% of the failures to come from 20% of the issues. Our single pin chart doesn't necessary adhere directly to this guideline, but you can see that the 10,7,4,6, and 9 pin make up 82% of our single pin leaves. It's obviously no surprise that the 10 is nearing half of all our single pin leaves for the year to date.
Taking that one step further, here is a pareto by single pin misses.
As would be expected, we also miss more 10 pins than any other single pin. We leave the most, we miss the most. But, does it mean percentage wise that is what we miss the most of?
Answer: Fuck yes it does. From a percentage of single pins missed (chart below) we also have the worst conversion rate on the pin we leave the most of, missing almost 30% of our 10 pins on the year, followed closely by the 7 pin at 27%.
In conclusion, while individually we may have single pins with a worse conversion rate than the 10 pin (for me it's the 7 pin), the best plan of attack to collectively increase our scores is to bump up our conversion rate on the 10 pin.
Second conclusion, the 10 can suck my dick in hell.
I think this is awesome. It's inspired me to do some chart-y things regarding the other statistics. It's also inspired me to go out and practice spares. If I could cover my ten pins and stop leaving messy splits, I could be so much better and, as a result, out team would improve. This is fun.
