What levels is coaching no longer worth while?

[TheDna]

I would get a coach when i cant beat the limit i play anymore. Say you play 200k hands nlh2/4 and 3/6 and get results around 5-8ptbb but you just simply cant make the jump to 5/10 cause you get beat up badly every time you try or at least dont get very good results. Thats imo a good point to get a coach, i would heavily cosider how much you earn and have to spend for a coach too.
