how to calculate number of points/sec for HDL64E_S3D

edit

packet rate mentioned for 64E_S3D is 5800. For each packet there are 32*12 laser points. With this calculation, number of points generated per sec for this should be around 222k. 5800/(600/60) * 32 * 12. Manual says that number of points generated per sec is 133k which is same as S2. Also when I check with veloview and export one frame to csv, it shows 105k points. For S2, packet rate is 3742 and it correctly gives us 133k by 374 * 12 * 32. Whats different with S3D ? what am i missing here?
