Commercial break lengths vary so widely that there is no "perfect" number of Skip button presses. Try 7 quick presses to get you past the first few minutes then use fast-forward to scan through the remainder. Try 9 presses to skip all the ads and use Replay or Rewind to adjust to your intended resume point.
According to my VideoReDo outputs, 30-minute programs have 10 minutes of ads (three 3- to 4-minute breaks) and 60-minute programs have 18 minutes of ads (five breaks) on average.
I've noticed the evening news on ABC, CBS, and NBC don't begin their ads until 15 minutes in, then there's a barrage of 3-minute pharmaceutical ads every 3 minutes.
Jimmy Kimmel Live gives you only 5 minutes of content over a 15-minute period toward the end of every episode.
The CBS news program "60 Minutes" starts with 5 minutes of previews and ads then ends with 5 minutes of ads which compacts the breaks inbetween closer together.
Most networks place the ads at the 15-minute marks of their one-hour programs so using TiVo's skip-to-tickmark feature tends to put you right at the start of a torrent of advertising.
In general, you'll get accustomed to which method of skipping ads works best for the individual programs you regularly watch. Sometimes fast-forwarding is better than using the Skip button and vice versa.
