for me

[color=red]a. For me, acting without improvisation is bad acting.
b. For me, acting without improvisation will be bad acting.

c. For me, an acting method that strictly forbids improvisation results in bad acting.
d. For me, an acting method that strictly forbids improvisation will result in bad acting.

I feel that there are two possible meanings here:

  1. I believe that acting without improvisation is bad acting.
    and it could mean
  2. If I act without improvisation (use a method that strictly forbids improvisation) the result will be bad acting.

I would say that (1) can only mean (a) but the others could have either meaning.

Am I correct?

Many thanks.

I don’t really see any difference in meaning between your 1. and your 2.
