1 sec block time,
2 min epoch,
50% saturation instead of 80% (this is something I am not clear yet on the reasoning and impact).

It's a 3-second block time, with 1 second for computation and remaining for propagation, validation, and voting. Kept the block saturation at 50% to start with as a safe-guard for weight calculations. This number can be increased later as we improve the benchmarks and hardware recommendations.
