Sorry for my late reply,Coca.
I have to admit that here lately I haven't been putting too much effort into pick3 due to my busy work schedule.
Any one single strategy is difficult to master which is why I try to look at things on multiple fronts.
Here is one possible solution that can improve your game:look for digits that are hitting over short term trends,these are indicators of digits trying to balance things out.I liken it to riding a wave out in the ocean.Once those hot digits/wave die/s out jump on the next hot digits/wave that come/s along.
Very trendy/hot digits have a way of entangling themselves with other digits that make up the pair as in Quantum Entanglement.Quantum Entanglement exists in Quantum Mechanics so it has to exist elsewhere theory wise that is.
Reduction modeling plus Quantum Entanglement coupled with my QED algorithm is how I arrive at my reduced QED pairing system.Its VERY VERY difficult even with my QED algorithm to get the percentages right everytime.
So it short: stay on your toes about certain digits that all of a sudden become hot over the short term (no more than 3 or so digits)...stay on the lookout for Sums that are realllly inflating past thier 2.5 value.
Good luck ....
