30vs120 layout step in a row coil winding video experiment(standart winding style)

Ok, I am am unclear on what the variables 30 and 120 refer to? Is this turns per layer? If so, what was the bobbin height and AWG of wire? What was the theoretical correct turns/layer? Without this information I am not sure what I am to make of this. thanks for the data....making 63 and 66 T-bird pickups at ThunderBucker Ranch

By the way another fact: people try to make PAF clone with hand winding style. With all things being equal they say it sound not like original. And that all is because when they use hand winding style the wire scatter is accidental that looks very similar to 30 ls winding from experiment above. When they HW they have less mid range frequency and they say that HW PAF sound softer.
In fact RP in that case is higher that makes sound a bit darker then original. But still you can make identical or even better PAF(more brighter sound) if you have enough experience and knowledge that you can get from this videos if you look closely here.
With respect

Whether it is possible to apply that 101 on pickupmaking in real life is another thing and open for debate but cudos to MrCandy for doing the videos and sharing.

I will know tomorrow ,i just ordered another spool this morning"UP here in the Canada we shoot things we don't understand"

HEY!!
Am I the only one here who watched the whole video?
Y'know, the one where the two coils had close Rdc and inductances,
but the 120 winds/inch one had a resonant peak (RP) a whole 2kHz lower than the 30 wpi one?
Our man just quantified what everyone's been talking about for years:
wide scatter wind means extended high frequency response.
30 120 wpi winds per inch Rdc 6654 6675 ohms DC resistance L 2.340 2.351 Henries inductance f 19430 17860 Hertz resonant frequency C 29 34 picoFarads distributed capacitance
The lower resonant peak is most likely from greater
distributed capacitance since the other electrical specs are so close.
Capacitance was calculated from the usual first order approx
for LC parallel reactance: 2*PI*f = sqrt(LC) , and solved for C.
C = ((2*PI*f)^-2)/L
That's the easy stuff. Maybe the EE types can add a few spices to the stew."Det var helt Texas" is written Nowegian meaning "that's totally Texas." When spoken, it means "that's crazy."

Yes, It was possible to just conduct experiments and not just talk for years.
By the way next thriller will be "PE vs Polyurethane": This theme is also discussed for decades and we really want to close it
with tests, measurements, specifications sound samples and other features like for example blind vote "Guess where..."

Our man just quantified what everyone's been talking about for years:
However, it is incorrect to attribute any significance to this. Here's why:
Let's assume that the capacitance has changed by 5 pf as your table shows and that the cable has 800 pf. The resonant frequency depends on the square root of the capacitance. So the change in resonant frequency from the winding is about 0.3%. This is hardly significant. If you bought 10 "identical" cables, you would probably find more difference than that!
So winding for really low capacitance has no practical significance.
