Do you require your final list of numbers to have passed every filter, or do you allow leeway?
I like the way most "good" systems are set up. They allow us to check or un-check the different filters......according to the situation as an option.
I feel about filters in two ways..... as a tool to bring data forward or reduce the data......and as guardian sensor.
The most important role of a group of filters is often the role of an "Alert Sensor". That's one of the reasons I always say.....the more watchful filters we have out there.... the better.
Even when filters are calm and not alerting us to any imminent data situations ......that's good info too isn't it?
All filters should be on all the time.....as many as we can find ....and it should be our option about how to use them or not.
The data should be updated after each draw so those filters can be used as "tracking sensors". Filters that actually light up when they approch certain alert zones that I set up as options ......they are the best...... they are the zones such as the "Magic Six" ......six times the expected math average hit rate for example.
I don't use all of my filters at one time ......but I have used them all at one time......or another. LOL
The only real failure .....is the failure to try.
Luck is a very rare thing....... Odds not so much.
Odds never change .....but probability does.
