Low latency wagering

[turfmonster]

First post on the board so please go easy. I have a quick question regarding the availability of pool information to make the most informed decisions with respect to horizontal and vertical wagering.  Given the advances in technology (i.e. Flash Boys as a mainstream market example), why as horseplayers do we settle for odds changes after the first quarter or drastically different probables vs. actual payouts? In essence, what I am asking is do I live in the stone age with imperfect information or is there a way to get better information in the market? I am one who believes fully in the Bet Fair model to give horseplayers the flexibility to both make and take odds allowing for more liquidity on the exchange. I appreciate any guidance the board can give.
