Da farko dai, adadin zagayowar da masana’anta ke bayarwa ya dogara ne akan gwajin matakin tantanin halitta guda. Rayuwar tantanin halitta ba zata iya zama daidai da rayuwar tsarin fakitin baturi kai tsaye ba. Bambanci tsakanin su biyun shine kamar haka.

1. Tantanin halitta guda ɗaya yana da babban yanki mai zafi da zafi mai kyau. Bayan an kafa tsarin Pack, tantanin halitta ba zai iya watsar da zafi da kyau ba, wanda zai lalace da sauri.
