Another danger in just following your guide can come up if you and the guide were not together on the prior dive. In my recent trip in Providencia we dove down to 43.3m/142’. On the second dive we were given a different guide because the first one was having sinus issues and our new guide had stayed on the boat during our first dive. On the second dive I noticed that the 2 other people in my group did not seem to be checking their computers and when my NDL was getting low I signaled to my computer and I went up a bit. The guide seemed to realize that his NDL was probably higher than the other divers in my group and rounded them up (one with difficulty).
Ironically I would hit deco on a later dive that week because I got distracted/careless and braced narced
