No, the total uf value of all of DF's caps added together is the cathode bypass capacitor value.Using smaller "side caps" is a different thing.
Bypassing a tube's cathode is one thing, "side capping" the cap used to bypass a tube's cathode, in an attempt to change or "fix" the "deficiencies" of capacitors, is another.
We also see side capping used on power supply caps and coupling caps in a attempt to improve some attributes of the main cap.
Bypassing a cathode (to the lowest frequency of interest) is about preventing local current feedback and restoring the tube's plate resistance.
Bypassing a cathode to less than the lowest frequency of interest is "Frequency Compensation".
Again, side capping is a different thing.
