I think those websites give you a great starting point. Start with a dose using a 60g/1L ratio and adjust to taste. For V60, use around a 3min brew time with a 30ish second bloom and adjust grind to hit time and good extraction. For pouring, it is easier to pulse pour and keep it near the center of the bloom. Especially with the V60, keep the pours as gentle as you can and be wary of the edges!
