How much would I need to raise a crockpot insert to satisfy the opinions of Rav Shlomo Zalman Auerbach and Rav Elyashiv? Is there an approximate percentage?

ב"ה Shalom After reviewing the opinions of Rav Shlomo Zalman Auerbach zt"l (מנחת שבת ח"ב ל"ד:ה)and Rav Elyashiv zt"l (ארחות שבת חלק א , עמ' תקמ, אוצרות השבת עמ' תקי"ז) I saw there is no mention of percentage, but what is required is that the inner pot is lifted a bit and sticks out in a way that it is discernable that there is a space between the inner pot and the outer pot. Enjoy your Cholent . All the best ה' עוז לעמו יתן ה' יברך את עמו בשלום
