Here's a good BALO check (unfortunately it doesn't happen all that often). NOTE: I've been testing all races except MSW, MdClm and 4-horse races.
Dirt races with the Red Running Style E or EP on the My Hcp screen. Horses with Running Style (RS - 402) 4 and 5 with Early Speed points (ES - 202) 0 or 1 Speed points only win about 10% of the time.
Turf races with the RED E (NOTE: I tested GPX and TAM). Horses with 0 or 1 Early Speed points only win about 10% of the time.
GPX Tapeta races with the RED E. Have tested the last 28 Tapeta races with the RED E-- have not come across a horse with 0 or 1 Early Speed points that won.
It takes a pretty good horse with 0 or 1 ES points to close and win a Running Style E race.

I look forward to hearing more of this tomorrow.

Flip-side. 25 Dirt races at MVR, PRX, GPX and TAM (no MSW, MdClm or 4-horse races). RED Running Styles EP, LP and SR. Only 1 winner with 8 or 7 ES points.
16 Turf races at GPX and TAM (EP, LP and SR)-- no 8 or 7 ES point winners.
15 Tapeta races at GPX (EP, LP and SR)-- only 1 winner with 8 or 7 ES points.
Sample size is small. But it does appear that ES 8 and 7 front runners struggle when the RED Running Style is not E.
