Kusiyana Pakati pa Mlingo wa Kuphulika-Umboni wa AT6 ndi BT4

Chiyembekezo chotsimikizira kuphulika kwa Zone A ndichotsika kuposa cha Zone B; komabe, kalasi ya kutentha T6 imaposa T4. Chifukwa chake, sikoyenera kunena kuti wina ali ndi mlingo wapamwamba wotsimikizira kuphulika kuposa wina.

Ndizolondola kunena kuti chilichonse chimapangidwa kuti chigwirizane ndi malo omwe amatha kuyaka komanso kuphulika.
