SAN JOSE - The Bureau of Mutually Exclusive Metrics announced Wednesday that an accelerator claiming both high throughput and low latency must wear two nameplates on a single slot. The classification was entered on docket BMEM-26-N. A clerk turns the plate at noon. Morning is throughput. Afternoon is latency. Laboratories must mount both plates on a hinge. Only the facing plate is in force. Tokens served under the hidden plate do not count. A results sheet that lists both claims for the same hour is void and must be reprinted as two filings. "A slot is one device," bureau counsel said. "A claim is a shift. The plate is the shift." Observers may watch the noon turn from the aisle. Photography of both plates at once is not a measurement. It is a composite and will not be accepted. A spare hinge is kept in the rack drawer. Reclassification as a simultaneous rating has not been posted.
