<thinking>Let's approach this step-by-step:
We should reason through this step-by-step (CoT):

Step 1: What does the problem instructing me to do?
Determine the amount of letter "f" in the string "Isochronous"

Step 2: Deconstruct the word.
I-S-O-C-H-R-O-N-O-U-S


1. I
2. S
3. O
4. C
5. H
6. R
7. O
8. N
9. O
10. U
11. S

Step 3: Determine the positions of the letter "f".
The letter "f" does not appear in the word.

Step 4: Enumerate the letters.
R: 1, U: 1, S: 2, I: 1, N: 1, H: 1, O: 3, C: 1

Step 5: Inspect the letters we quantified.
The chosen letter was "f" and there we identified 0 total.</thinking>
