I'd second Ramon's approach to using half the DTV when using that number for input into manual entry programs. Doc's formula for Val always used half the DTV, although Val3c now effectively uses the whole DTV (due to the TM data source change last year). Spec160 and RDSS use half the DTV by default.

One of Doc's older papers on Incremental Energy exertion made the case that a fair portion of daily final time variation (i.e. DTV) was not due to inherent surface speed for the day but rather due to the match up of contenders in a given race. Hence using half that DTV.

I don't have an opinion on capping the net DTV at +-9, though I'd love to see any rigourous study...
