Set it today to about 5*10**16 at/sec. Life time became 13-14 min. Still, they could store up to 120 mA, but data acqusition system chokes on anything above 90 mA. Took 3 runs (12234-12236) with current limits 12 0->80. After that reducded the limits to 60->90 and took some more runs (12237-12240, 12241-43). WC counted at about 70, BQM - 130,155,492(top),278(bottom).
