How much should i feed my 1.5m children's python?

how much should i feed my 1.5m children's python One snake specialist thinks i should be feeding her 8cm-10cm (head to tip of tail) rats every 7-10 days depending on the season so they dont rot in her and another snake specialist thinks i should be feeding her rats weighing more than 100grams over double the size (a little less than 4x the size of her head) every 7 days so her bowels dont prostrate ... I fed her a medium rat today 75gram-100grams and i cant even see the rat blob they both have such good reasoning what do i do??
