Your methodology?
I have used a computer in varying degrees to aid my handicapping. In the mid 1980's I used the PC to download handicapping aides along with the printed DRF. In the early 1990's I still used a racing form or racing times but also handicapped every race with ThoroBrainX. After ThoroBrainX left the market When HSH became available I used it in conjunction with the printed form. I found myself relying more on my analysis from the printed form.
When I started betting to make a living I became wary of making changes as there is a fine line between winning and losing. My primary tool remains the DRF (formulator) which allows me to print a customized form, watch replays, maintain trip notes and quickly review result charts. When Dave introduces a new AI product I believe I will become much more PC dependant
