Goal: detect maximum number of strokes accurately with minimum number of signals
Efficiency: Ability to accomplish something with the least amount of time and effort.
Effectivity: Actual production of the intended result.
Efficiency = Strokes Detected / Signals Sent
Effectivity = Strokes Detected / Signals Sent - Strokes Detected
As you know I've been evaluating the above and have found it useful in tweaking my station to get the number of signals used high and the number sent low. This was proving quite succesfull. Today there is no lighting activity in Europe to speak of (the Europe static map had a count of 7 (seven) a moment ago). My station sample produced this:
As there is no lilghtining all the measures are zero, yet stations are still sending 1000's of signals/hour. This can really only be local noise. We could rename "Effciency" to "Waste" and invert the calculation trapping the divide by zero problem to return 100%. Trouble is everyone above is 100% wasteful which, while technically correct, isn't useful. Is there some way to have a meaningful "Waste" value when the Used count is zero?
Maybe an "allowable noise" number? (<Sent> - <allowance>)/<sent> trouble is if your under allowance you end up with a negative "waste".
Ideas?
