I looked at yesterday's Sandown meeting.

NSW tote first, then best tote odds, then increased win Percentage with Best Tote.

$1.70 $1.90 Best Tote plus 29%
$8.90 $9.10 Best Tote plus 5%
$20.70 $22.90 Best Tote plus 21%
$3.40 $3.70 Best Tote plus 13%
$4.30 $4.90 Best Tote plus 18%
$6.00 $6.80 Best Tote plus 16%

I'll suggest that 6.1% LOT is wiped out using Best Tote.
