Counter hit inconsistency

Hi Guys,

I am experiencing inconsistency around my forehand counter hit.  I can consistently go for weeks counter hitting very well and then I start to lose technique and it gets worse and worse...mostly due to me getting frustrated and searching for the correct stroke (given I think it is the simplest shot).

Would be interested in your thoughts around how to best deal with this.  Should I keep slogging away at the shot until it comes back into form or just let it be for a little while? ...or any other recommendations.

Cheers
