Muchikamu chechipiri cha2018, takasangana pakuratidzira kweCPHI. Panguva iyoyo, mutengi achiri ne zero process uye zero formula.

Muhafu yekutanga ya2019, mushure memakumi emakumi emakumi efomula yekuvandudza masampula, chiyero chebudiriro chaive chidiki kwazvo, asi isu hatina kukanda mapfumo pasi. Takaedza mafomula evatengi 121 nguva, 7260 maminetsi; midziyo samples 232 nguva, 13920 maminitsi, izvo zvakatora makore maviri.

Muna 2018-2020, isu tinoperekedza vatengi kuti vakure kubva pachinhu chimwe kuenda kumafirimu ekurongedza. Mutsetse wekugadzira waunzwa uye kudzidziswa kwakapedzwa muhafu yechipiri ye2020.
