Binotto is perplexed as to why others have praised his team's potential when he believes it is impossible to know where everyone stands.
Due to a late red flag caused by Valterri Bottas's stoppage, Max Verstappen only had 20 minutes for a final time attack.
Despite this, the Scuderia and both of its drivers had another productive day, logging a total of 114 laps.
In second place was former Red Bull and current Williams driver Alex Albon, who was half a second behind the Monegasque.
Every team faced porpoising to some degree during pre-season testing, with Charles Leclerc admitting it made him feel slightly ill.
However, Charles Leclerc also warned that pre-season speed means nothing at this point and Ferrari still have work to do.
The effect is unlike anything the current generation of drivers has seen before, as ground effect cars were banned in the 1980s.
Last year, the Spaniard outperformed his highly-rated teammate Charles Leclerc, finishing best of the rest behind only the Mercedes and Red Bull drivers.
Speaking at the car launch of the F1-75, Charles Leclerc said he was happy with how the team have worked on their new F1 car.
The new F1-75 retains the team's iconic red colours, but features black front and rear wings, harkening back to the 1990s.
