Using `rampUsers` per ELB Doc?

Looking at Best Practices for Evaluating ELB, I read:

Once you have a testing tool in place, you will need to define the growth in the load. We recommend that you increase the load at a rate of no more than 50 percent every five minutes. Both step patterns and linear >patterns for load generation should work well with Elastic Load Balancing.

I thought to use rampUsersPerSec from, but I was thinking of:

time (seconds) users
0 0
5 5
10 8
15 11
20 17
25 25

Note that 51.50 rounds to 8, 81.50 rounds to 11, etc.

So, I’m trying to ramp up users to match the ELB doc.
