Brewlab yeast slope starter

[ssparks]

Going to use a Brewlab yeast slope in my next brew and just want to confirm the process. I see looking on their website that I start with 3 table spoons of dme in 300cm of water to get the starter going. I'm brewing a beer with a OG of 1055 so do I need to do a second starter after 24-48 hours or will the single 300ml starter be enough?

I'd personally say should be OK - I did a 1065 beer before with just one starter - but I did make a litre of starter for that. But just the one.
