Just to be clear; There is no "in the hour your might get visited by anti-doping", as you named it, in out-competition testing.   Out-competition you can get a test at any moment during the day; also outside the hour you mention you can be found on a fixed place in the whereabouts.  Your whereabouts also mention where you train, where you sleep.  They can find you in these places and do tests at any moment.
		
		
	 
It really isn't as random as you're making out. Lets break WADA's protocol down:
Details given in whereabouts
1. Home address, email address and phone number
2. An address for overnight accommodations
3. Regular activities, such as training, work, and school, the locations and the times of these activities
4. Competition schedules and locations
5. A 60-minute time slot for each day where they’ll be available and accessible for testing and liable for a potential ‘missed test’
Item 5 is the only possible out of competition violation possible in as much as if you are NOT there for that hour to be tested, it's specified & classed as a missed test. Items 1 - 4 if you are not there, cannot under WADA code be considered a missed test strike. WADA even explain it as such:
"Remember that all athletes can still be tested anytime and anywhere. However, for RTP athletes, 
a missed test may be recorded if you are unavailable during your declared 60-minute window"
