Can someone help me in understanding #dynamicfare for below details -

Train #02095
From #CSMT
To #BSP

Per my understanding, there are 42 berths allocated between CSMT & BSP.
Dynamic fare, would begin only after first 50% of berths are filled. Meaning first 21 berths would be at regular fare w/o additional fare. Post that, 10% of addition until 1.5x.

What I observed is - for first two berth only, fare is regular and post that - dynamic fare comes.
