Narrative:
After turning on to final for runway 28R we got a TCASII 'reduce descent' caused by an overtaking bizjet behind us on approach for runway 28L. We had the bizjet in sight on base leg and made our turn to final well inside him. He had requested and received clearance for a long landing from tower. We were in the process of slowing to our stabilized approach speed for landing on the approach end of runway 28R, and apparently the bizjet was later than we were in slowing for landing. He never passed us on final and both planes landed safely. This is the 2ND time, on 2 consecutive days, that we got a TCASII RA on approach into sfo. Both were in excellent VFR WX conditions. Is bay approach reducing arrival separation too much, when visual approachs are in use?

Title: ACR X TCASII RA WITH BIZJET WHILE ON VISUAL APCH TO MULTIPLE RWY OP PARALLEL RWYS.
Narrative: AFTER TURNING ON TO FINAL FOR RWY 28R WE GOT A TCASII 'REDUCE DSCNT' CAUSED BY AN OVERTAKING BIZJET BEHIND US ON APCH FOR RWY 28L. WE HAD THE BIZJET IN SIGHT ON BASE LEG AND MADE OUR TURN TO FINAL WELL INSIDE HIM. HE HAD REQUESTED AND RECEIVED CLRNC FOR A LONG LNDG FROM TWR. WE WERE IN THE PROCESS OF SLOWING TO OUR STABILIZED APCH SPD FOR LNDG ON THE APCH END OF RWY 28R, AND APPARENTLY THE BIZJET WAS LATER THAN WE WERE IN SLOWING FOR LNDG. HE NEVER PASSED US ON FINAL AND BOTH PLANES LANDED SAFELY. THIS IS THE 2ND TIME, ON 2 CONSECUTIVE DAYS, THAT WE GOT A TCASII RA ON APCH INTO SFO. BOTH WERE IN EXCELLENT VFR WX CONDITIONS. IS BAY APCH REDUCING ARR SEPARATION TOO MUCH, WHEN VISUAL APCHS ARE IN USE?
