Agree that 50 dives is the best time to start thinking about Intro to tech, UTD Essentials or GUE-F type courses.
Not for all - it entiely depends on the capability of the diver concerned and the quality of the diving they have done during those first 50 dives.
That said... a further 50 dive 'build-up' focusing entirely on developing the right skillset and mindset, supported by appropriate introductory training is perfect preparation for tech training.
