Do some math yourself

Obviously Dr. Hiraki needs to leave the university for a while and to visit some school - he needs few lessons in reading and mathematics:

a. there are many many standards for 10Gbit Ethernet physical layer (OSI L1) but the most popular one does support two bitrates - 9.953 and ... 10.3 Gbit/s;

b. 10% over the achieved 9.08 makes 9.988 Gbit/s which indeed cannot be exceeded on a 9.953 but should not be a big issue for a 10.3 Gbit network.

If one does not trust the biggest team blog on Earth (http://en.wikipedia.org/wiki/10_gigabit_Ethernet#LAN_PHY), just looking at some vendor specifications (http://www.digchip.com/datasheets/parts/datasheet/368/PM5390.php / http://www.pmc-sierra.com/products/details/pm5390/) should prove the existence of the ten-plus-epsilon bitrate.
