"Pausing" program make sense?

Programming Examples
1

If i do not need frequent execution of some commands, is there any practical sense to pause them? My code can be executed every 10sec, most of it even once in 5 min minutes actually. Does it save anything?

20 IF NOT ( INTERVAL ( 00:00:10 ) ) THEN GOTO 40
30 VAR11 = VAR4 / 1000 * IN2 * 100
40 REM END

This is a little easier for the next guy to debug five years from now.

10 IF INTERVAL ( 0:0:10 ) THEN VAR11 = VAR4 / 1000 * IN2 * 100

Don’t forget to give all the items names to make the program even easier to maintain.
