A critical aspect to consider in this third movement is the matter of timing. Firstly, regarding all fermatas: in the Classical period, a fermata should generally be understood as extending the notated duration by approximately 1.5 times. Consequently, when a fermata is placed on an eighth rest, it indicates a very brief breath, yet many performers tend to take a prolonged pause at this point.

For instance, if the fermata on the eighth rest in measure 8 is held for an excessively long duration, then, following that interpretive convention, the fermata in measure 55 would also be extended considerably.

Furthermore, as exemplified by the fermata in measure 77, when an eighth rest follows a fermata, one must count the eighth rest immediately after the sound ceases and proceed; it is imperative not to take a quarter rest's worth or more of time here.

When Haydn places a fermata on an eighth rest, it truly signifies only a very slight breath. For a reference recording, please listen to the performance by Mr. Kousuke Kita, which is recommended by this Piano Encyclopedia. His performance demonstrates the correct timing.
