Interesting. I do sometimes wonder about "groups" as such and more think it is a collection of 100s of individual stories. But yes it is still certainly interesting ( and can be instructive ) to look at those who have followed similar paths and these paths that have most usually led to later success or not so much.

I do think there is certainly now a very string case for Emily and Jodie concentrating mainly on seniors this year with restrcting juniors to at most Slams and maybe the odd warm up event.

Although Garcia, Mertens, Cohen and Wozniak ( not a big number as it is and in cases dating back a bit ) did play juniors in the year they turned 18 and ended that year ranked in the junior top 10, only Mertens played much more juniors than the Slams with a fairly even split of about 10 junior and 10 senior events. The others very much played predominately seniors tournaments and it is a point that Elise was born in November so all things being equal would transition a bit later in time as against others born in 1995.

So overall, again while there can be real dangers in considering one size fits all, I think players who have really progressed as seniors have overwhelming been concentrating on seniors in the year they turn 18 ( and many well before that ) with juniors at most limited to the big junior events. If you transition markedly later than that norm for top players you are playing a bit of catch-up.

As I said most of the names mentioned above as still playing juniors not only mainly played seniors but in cases were senior top 200 ranked at the end of that last junior year : Garcia WR 146, Wozniak 190 and indeed Bouchard ( also only big junior events concentrated in that final junior year ) WR 144. Mertens ( who was much more steadily transitioning ) was WR 577 and Cohen WR 469.

So, maybe play some of the biggest junior events, in particular the Slams, if you fancy them girls, but now be playing plenty senior events.

Emily is scheduled to start at Vanderbilt Autumn 2017
