write-read dependency cycles over read-write registers, and the append test uses appends of unique elements to lists. We include realtime dependencies (e.g. T1 com- pletes before T2 begins) in our analysis tests, default-sized clusters reached a fully-replicated state in 1-2 minutes; regions capped at 500 elements might fail to converge after 80+ minutes. When a net- work partition occurs under those conditions
