Reports the highest rate of authorization requests per second SSG has recorded for TAL, with each new peak overwriting the previous recorded maximum. Because it's continuously overwritten rather than accumulated, this value only tells you the single highest burst seen since the last reset via cssgTalResetAuthRates, which is exactly the number to compare against cssgTalMaxAuthReqsRate to see how close the network has actually come to its configured throttling ceiling. If cssgTalMaxAuthRate shows 480 requests/sec against a configured cssgTalMaxAuthReqsRate ceiling of 500, the network is close enough to that ceiling that a modest traffic increase could start triggering throttling.
