dr. formulas are tricky, what orked last year may not work this year,,, on and on,,, statshark is average, Statfox is better,
the ones useing Excel spreads, they have just isolated a few Key stats that they feel holds more power.
hmmmm whats the answer?? you have to find it on your own bro.
if there was a magical angle, (ive heard of several) they keep it hidden, and wont tell anyone,,,
do good research, put in time, use common sense,,,,, blah blah,,,,
good luck
