Hi !!

I play Clementi's Sonatina Op.36 n°1.
I have a question regarding trills in 2° movement. I will describe that specific part, the best i can

LH plays a triplet C-E-G (that is, 3 (1/8) notes that fit a quarter note). At the same time, RH makes a trill on another G. Right now, i play a very simple version, like this:
RH: AG - AG - FG
LH: C - E - G
That is, a single trill (AG) for each of the first 2 notes of the LH (C and E), and the 2 finish notes of the trill (FG) fitting the third note of the LH. Is this clear?

So far, so good..this is not complicate. However, i should go a step further, and add another cycle to the trill. My teacher suggests to play 3 cycles instead of 2 (AGAGAGFG). My problem is that this way the correspondence between the notes on the bass and those of the RH becomes much more complicate (not just 2 RH for one LH, like now).
It can even be more manageable for my brain to make 5 cycles (6 with the finish, that would be AGAGAGAGAGFG), that is 4 RH notes for each LH. But this has the drawback of being very fast, which is in turn another complication.
So, to play "3 cycles + finish", do you just have to uncoordinate both hands and just think:
"AGAGAGFG" must fit in "CEG"?
How do you manage this?
Sorry for being so unclear, but it is difficult for me to speak english, and writing music in text form does not facilitate the issue
