On most dive operations, a 1,000 dive+ diver would
hope to be buddied with a 200+ diver. That would be about the best you could expect. Only a very small percentage of divers reach 200+ dives.
Additionally, I would expect a 200+ diver to be pretty good, well able to handle pretty much anything on a recreational dive. If I need more than that in a buddy, I will bring my own.
The reason people fear the newbie is their lack of skill required for handling the dives you want to do. It is hard to tell by the number of dives, though. Here is a story that will illustrate the issue
perfectly:
Two friends and I were diving in Akumal, Mexico. The dives there required boats, but the trips were very short, so the dive operation did 4 one-tank dives a day. On our third day of diving, we had a DM we had not had before. As we walked back toward the shop after the first dive, the DM talked to the three of us. He said he noticed we were much more skilled than the other divers on that dive. He said we were the only three people signed up for the next dive. Would it be OK if he took us to a much more advanced site, one more befitting our skills and experience? "You bet!" we responded.
As we suited up for the next dive, we saw another couple suiting up as well. They had signed up for that dive late. When we got to that more advanced dive site, it was obvious in the first minutes of the dive that the wife was not up to it. Her buoyancy control was miserable. The DM took 5 minutes of our dive to give her a buoyancy lesson while we watched. Even when done, she didn't have a clue. We spent the entire dive floating over the top of the reef, and down below I could see the narrow canyons and swim-throughs the DM had intended for us. It was not a good dive.
After the dive, the DM apologized. He said that the other couple only had about 25 dives total, not the vast experience the three of us had. I pointed to my two friends and said, "I finished certifying them on yesterday. The dives you did with us today were their first two dives as certified OW divers."
