EB1C current : is it concurrent filing or concurrent processing?

[L1A_asp]

We have submitted EB1C I140+ I485 docs (along with EAD and AP docs and medical reports)
Doubt is :
Will all I140 and I485 adjudicated together ( texas center shows 24 months max----So both in 24 months + or -ve couple of days??)
Or only filing is concurrent processing is individual ?Meaning only I140 will be processed in max 24 months.i485 will be done in 50 months ( as per current processing timelines)
