Question on Cardas Frequency Sweep & burn in LP

Does anyone use this LP for breakin in cartridges ?
How long do you guys run in it the lock up mode ?
What is the difference between these tracks ?

Track 2. 20 locked grooves, lateral modulation (mono)

1/2” wide, unmodulated plateau

Track 3. 32 locked grooves, vertical modulation (out-of phase)

1/2” wide, unmodulated plateau

Track 4. 20 locked grooves, lateral modulation (mono)

Which track of the 3 is best for breakin in a cart ? or the tonearm wires ?

Thanks for the help,
nolitan

Stressed? Me?
While my audiophilia does cause occasional stress, it is never around whether I am using the "best" test LP. I think Mr. Cardas realized that the best way to enhance the profits from his first test LP was to make another.

I use the Cardas cuts 2a, b, and c of the first version LP to "wake up" cartridges I have not used in a long time or to break in a new cartridge. The results seem to be beneficial, emphasis on "seem". But how could anyone have anything but a subjective opinion about the relative merits of each of the three break-in LPs you mention? One cannot do any sort of controlled comparison, because any given cartridge, once it's been run any single one of the 3 discs, has been changed from its new or unused state. It's kind of like wondering whether you should have married this girl or that girl (or guy) post facto.
