I find the TF performance unusual.
i bet that there are some results that don't have a TF number recorded and it is coming back at 0 and that why it is comparatively bad.
just my opinion but i thought it would have come in at around 12% LOT
and certainly better than the tabs.
the fact that best tote + sp improves best tote seems to confirm this

i have always said best tote is 6% points better than single tote and your number of about 6.5% improvement confirms this.
that's why the sporting bet of best + 5% is so good.

now if we could just get them to take our bets.

thanks for the numbers
