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

Lew, I've found it easier and less stressful to flip between test records.

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.

Last year I had to have my VDH GLA III Grasshopper rebuilt by AJ. Because I have a better sounding turntable than the one the Grasshopper is on, I don't play it much.  It has around 45 hours on it total.  Top and midrange sound fine, but the bass is not what I remembered.

Recently I read that it may not sound best until it reaches 300 hours.  At that rate, I may never get the bass the cartridge is capable of.  So I will probably get the Cardas Frequency Sweep Record, and run tracks 2,3, & 4 locked grooves for 20 minutes each.
