Let β> 1 be a real number. For any x∈[0, 1], the run-length function r n (x, β) is defined as the length of the longest run of 0's amongst the first n digits in the β-expansion of x. Let {δ n} n≥ 1 be a non-decreasing sequence of integers and define E ({δ n} n≥ 1)={x∈[0, 1]: lim sup n→∞ r n (x, β) δ n= 1}. In this paper, we show that dim H E ({δ n} n≥ 1)= max{0, 1− lim inf n→∞ δ n⧸ n}. Using the same method, we also study a class of extremely refined subset of the exceptional set in Erdös–Rényi limit theorem. Precisely, we prove that if lim inf n→∞ δ n n= 0, then the set E max ({δ n} n≥ 1)={x∈[0, 1]: lim inf n→∞ r n (x, β) δ n= 0, lim sup n→∞ r n (x, β) δ n=+∞} has full Hausdorff dimension.
