Meliorativ monitoring ma’lumotlarining ishonchliligi ular asosida chiqariladigan har qanday xulosaning aniqlik chegarasini belgilaydi. Maqolada hisobot shakllantirishda oldingi davr qiymatlarining ko‘chirilishi natijasida yuzaga keladigan nuqson turi ko‘rib chiqiladi. Bunday yozuv fazoviy ma’lumotlar sifatining standart tekshiruvlaridan muvaffaqiyatli o‘tadi — u to‘liq, fizik jihatdan maqbul, mantiqiy izchil va koordinatasi to‘g‘ri; uning yagona belgisi statistik xarakterga ega. Muallif tomonidan besh yo‘nalishli nazorat algoritmi taklif etilgan bo‘lib, uning asosiy elementi noyob qiymatlar sonining o‘lchovlar soniga nisbati (U ko‘rsatkichi) hisoblanadi. Algoritm Andijon viloyati Marhamat tumanining 2009–2024-yillardagi monitoring ma’lumotlarida sinovdan o‘tkazilib, uchta mustaqil nuqson aniqlangan: 2023-yil minerallashuv qatorining butunlay bir xil qiymatlardan iborat ekani (U = 0,006; oldingi yillarda 0,62–0,69); sizot sathi qiymatlarining uch yil juftligida takrorlanishi; hamda 2024-yil qatorida koordinatalarga ega bo‘lmagan to‘qqizta jamlanma yozuvning mavjudligi. Oxirgi nuqson chiqarilgach kritik zonadagi quduqlar ulushi 37,6 dan 38,3 foizga ko‘tarilgan, ya’ni nuqson meliorativ vaziyatni haqiqiydan qulayroq ko‘rsatgan. Nuqson aniqlanmaganda geostatistik modelda soxta «bir jinsli» yuza shakllanishi va integral bahoning buzilishi ko‘rsatilgan. Ma’lumotlar ishonchliligini ta’minlash reglamenti taklif etilgan.
