No I realise that, and I'm not speaking from experience. I'm speaking from what I've read from professionals' confessions.
First of all, the hide under the bed thing is for real. If you're "not" where you say you were going to be, you get a strike. Not only that but the WADA code also states that athletes have to be tested at certain times, etc. This then allows you more flexibility with what you actually use.
Second, I know it's not going to be 1 or 2 tests, but I just wanted to point out that "more or less" is irrelevant if the actual incidence of testing is low.
So if Australia did 178 tests in the year, how many athletes does that cover? I genuinely have no idea, but work it out and think - if there's 60 athletes, that's an average of 3 tests per year. 3 days out of 365 - not only that, but add in your 2 free "strikes" and I feel like it's not as "watertight" as people would like to think.
I agree with the idea that testing "lessens" cheating, rather than stopping it.
