72% internal rate of return

have sought and bought what i consider is cream of IT sector. wherever possible i prefer to use figures produced by company themselves v. analyst predictions. I made some notes from a recent AMM audio presentation. all figures refer to full yr FY10.
Rev 50m (up 15%)
EBITDA 17m (up 35%)(margin 34%)
NPAT(B4 sig items) 7m (up 48%)
Operating cash flow 19m (up 49%)
Gearing 13%
Free cash 4m/annum (pre-div)
Est. EPS 2.2c

But for me the crucial statistic (paricuarly for a rapid growth company) is that "Capital invested in new customers is recovered in one year and generates a 75% internal rate of return!!"
PS. exclamation marks are mine.
PPS.this typifies the strong return on investment/equity that IT stks can produce. How can a airline, retail chain, mine or bank match this sort of return? Possible but not likely imo.
