Hi all, I suggested, in another forum, that my success rate for my layout operations was 91%. I was very suprized by the number of fellow modellers who thought that was pretty low. Let me take a minute to explain how I arrived at that figure, then YOU take a minute, if you would, and help me complete this little survey, by adding your success rate, actual or estimate. Thanks! I define a "job" as randomly picking up one or two cars and running with them, and/or dropping them off somewhere. The engine which performs this task is also randomly assigned. I have 26 cars and two engines available for these operations. Five more switchers can help. 11 Locations (sidings and stubs) are possible pick up and drop of points. I use the Kadee magnetic ramps which delay uncouple for me. A goal is to never touch the train. Errors that count against my success rate are derailments caused by mechanical or operator error. Mechanical errors include track and turnout problems, dirty wheels and track, rolling stock with wheel, truck, frame or weight problems. Operator errors are me, asleep at the switch, or drunk... and sending a train the wrongway through a turnout, etc. Currently I have logged about 1,020 such jobs since 2/7/06 and my error rate is; Mechanical errors 3.7% Operator errors 4.2% SUCCESS RATE 92.1% :thumb: It is interesting to see the unforced errors fluxuate, where the mechanical ones are staying pretty constant. What's your batting average?
