FE Hoppy, in theory, you could shorten the ASD & TO distances to match the 2/3 of the RWY thus excluding the END. Relevant, for the take off, means either full stop or at the reference zero on the RWY in case of a aborted or continued take off respectively. Nowadays not difficult to do with the LPC performance software. Not sure if I'd recommend to do so as no accurate data is available on the aforesaid distances in relation to the RVR measurement portions. In reverse you can elect to perform a take off from the intersection excluding the TDZ RVR thus avoiding the assessment. Hope that helps.
