VPN Throughput 225Mb/s / # of VPNs?

Per the datasheet below Cisco states that you can up to 750 VPNs configured on an ASA 5520 with 225Mb/s throughput. What throughput can you expect as you add VPNs on the outside interface? Would it be 225Mb/s divided by the number of VPNs you put on that outside interface or can you get 225Mb/s sustained for each VPN?

If you try establishing more than 750 VPNs , which is the maximum VPNs possible it will drop those connections. But I have not tried it practically.
