I\'m not a regular sheet user. My main interest is  trainer patterns. In a previous thread a statement was made that a modern sheet player needs to include the use of trainer info into ones sheet reading. With that in mind has anyone thought of keeping stats on trainers productivity with horses exhibiting the variuos known patterens? Example: trainer X with horses off a new top, circling back, likely to bounce etc.Would this be useful, Could it be or has it been done? Just food for thought. LOU M.
