Solana proposes geo-aware leader schedule to cut handoff latency

• —At σ=10%, handoff gain rose from 15.8 ms at γ=2 to 33.9 ms at γ=50
• —γ=3 captures 65% of the γ=50 gain, γ=5 captures 79%, γ=10 captures 91%
• —Excess geographic persistence at γ=50 fell from about 61 windows at σ=2% to 23 at σ=20%
• —Solana chose σ=10% and a rational γ range of 3 to 7
