Personally I began in 2020 and now starting to work on this combo (I can do the individual elements, but doing them one after the other is a lot more challenging). In my first year, class wasn't regular because of covid, in the 2nd year I was only 'half consistent' too. Only started really being consistent in the previous year. I didn't have strength at the beginning either. Every persons process is individual but I guess if one is consistent from the start (even just training once a week) they might get it faster than me. I know a few people who started with me and are still intermediate but I also know people who were doing advanced/master stuff after their first 3 years. Flexibility comes very handy for all the tricks too and I find it harder to achieve than strength, so this will for sure help out a lot (important tip: make sure to work on active flexibility, not only on passive flexibility). Hope I could help :)
