It should be worth it, depending on your specific situation, in particular if you have 18yo trainees who can benefit for 2 full seasons. I use a lvl 6 trainer and lvl 6 youth trainer and the combined effect is more than a lvl 7 trainer. Nobody knows the exact improvement and it will be impossible to check unless you do another data collection project like the one years ago. All i know is that messing around for the first 4 weeks (had a level 4 YT and for one week even a lvl 4 trainer) I still got 19 pops in one season and there were reports of 21. That is a lot of pops.
So let's say it has a multiplicative effect on your trainer and it's like 2.5% per level (2.5% for lvl 2, 12.5% for level 6 and 15% for lvl 7), if your trainer would give you 25 pops over the first 2 seasons on his own, then a YT would add 3-4. It may be more and it may be less, but I think that's a reasonable assumption.
Ultimately it depends on how many and what kind of trainees you have: do you have low potential trainees? Lower potential trainees will cap anyway in a slightly longer time even without a YT. Does it make sense to spend around 200k per season, maybe a little more for a lvl 4 YT, to speed up training by 3 weeks in 2 seasons? It may be if you have many trainees. It definitely is, if you have HoF or MVP trainees and it probably is if you have Superstar trainees.
Keep in mind that if you fire a YT you will not have the drag on the economy that a lvl 1 staff member will automatically be hired in his place, so you can effectively replace this kind of staff much more easily than a trainer or a doctor.
