And you think the range of their overcalls is bigger then the range of their openings?
Interesting idea. I always thought that nothing has such a big range then an one of a suit opener in a natural system.
The range for openings is s.th. like 11-21. The range of a simple overcall is s.th. like 7-19 for many. But even if your range is 8-18 (in which case you may run into other problems, e.g. by doubling with a 19 count and a singleton major), that's effectively a wider range than 11-21. If you make a 11-21 opening bid, most of your hands will fall into the 11-14 range. If you make an 8-18 overcall, most of your hands will fall into the 8-13 range, a considerably wider range.
As for "senior citizens" having their values here, last time I checked Versace is a bit older than 30. So is Welland. Etc.
