New Hire Training Classes Added To One Path

Hello,

I am new to Rise/Reach 360. I am in the process of creating 13 modules, which will be in a training "Path," for our next New Hire Training Class. The 1st class will be about 10-15 people. It's a week-long training. We will have multiple New Hire trainings throughout the year. I would like to just add the subsequent training classes to the "New Hire Training Path" as the trainings come up but at the same time, I don't want the list of people in that Path to get too big or would that even be an issue? 

I wonder if there is a problem doing that way (just to keep adding to the one group) or would it be necessary or advisable to create a training path per training group? The idea of that seems a little daunting. 

I don't know if I'm over thinking this or not. I haven't gotten into the analytics of the quizzes and final exam for each class... if I keep adding the next training class learners to the same Path, will that screw up the analytics?

Normally I research everything myself but I'm on a SERIOUS time crunch and need any advise I can get, ASAP.

I hope this makes sense.

TIA
