Devoucoux Codes

Would someone be able to decipher the Devoucoux codes below and explain them to me?

Biarritz O
2025
AO
17 2A 3PC D3D SB 4+5 3.0

TIA!!

Not 100% positive but my understanding:

Biarritz O is the model
2025 is the production year
AO is their “wide” tree
17 - seat size
2A - flap (standard length/forwardness)
3PC - something about the girthing/billet set up?
D3D - panels (wider/more surface area on the horses back)
SB - scapula brush (remove foam over the shoulders in the front of the saddle)
4+5 - plus 5mm foam in the front portion of the panels over the withers
3.0 - standard foam in the back of the panels.

Thank you!!
