Data from E99-117, the ratio e/ ~ 23
If A ~ 0.1, and ratio e/ ~ 10with factor R~104 -> A ~ 10-5
(assuming 10% accurate correction for pion A) standard HRS analysis: R ~ 2 x105

SummarySummary
Required R{e/ will be possible to get with NIM + scalers. Time scale of six months to construct and test electronics. Best option is just 20% most complicated than minimum set. Modification of the Left arm cost $10k for glass and $40k for PMTs. Upgrade of detector in HRS-Left will help future DIS experiments.
