Similarly I've done multi leg transits many times (sometimes with so many connections they require 2 tags... I think it's max 4 connections on a single tag) and not lost or delayed a bag as a result of that alone. Very very rarely some other things have happened like aircraft downsizing or weather that caused delays, but even those have been years ago. Within the last several years the only baggage irregularities I've experienced were Priority tagged bags coming off the belt last. (and really annoys me quite badly in countries with long customs queues like NZ or Egypt when you could have easily been at the front of the queue of a 350 passenger plane / and multiple 350 passenger planes hitting immigration / customs at the same exact time).
