Market share for PE due diligence consulting firms

Curious if anyone knows the breakdown of PE due diligence revenue from the top consulting firms in the PE DD space: (Bain, Parthenon, L.E.K., etc).

Understood that at the junior level its not super relevant but I'm interested in knowing the relative magnitudes of different PE DD groups.

Bain // LEK, McK // Parthenon // BCG, Oliver Wyman // Other (e.g. OC&C, Roland Berger

Bain is 3-4x LEK/McK, McK is 2x BCG, fill in the blanks. That translates into something like: Bain 30-40% Mck 10-15% LEK 10-15% Parthenon 7.5-12.5% BCG 5-10% Oliver Wyman 5-10% Other 15-20%

 

It's directionally right. But it's a weird question. The PE DD "space" doesn't exist. You need to cut it up in their respective segments; i.e. sell-side vs. buy-side, Ops vs. CDD vs. FDD etc. There no point in the question.
