yes, dynamic uses algo B unless in high congestion, then it switches to algo A IIRC.
I don't think you should be triggering use of algo A in this test, so you should be fine using default algo, which tries to allocate as many TS as possible to the MS given is ms_class.
Are you really triggering allocation with algo A if you leave it as "dynamic"?.

I think it's fine to use the default algo and assume all PDCHs of the TS (you only enable 2 per TS) will be used. If you don't want that, you can change the ms_class you send in bssgp_ms_racap_egprs_def to one which only allows 1 TS. This way you test one specific thing instead of mangling with the allocator here.

See https://www.rfwireless-world.com/Terminology/GPRS-mobile-multislot-classes.html

gprs_ms_class 1 allows for 1 UL TBF and 1 DL TBF at the time. Whatever algo you use, it should allocate 1 PDCH to it. See right now you are using "gprsmultislotclass := '00011'B," (PCU_Tests.ttcn:135).
