For my calculations I have defined space efficiency as (area directly covered by a mining drill)/(total area). This gives a unfeasible design covered entirely by drills a space efficiency of 100%. For the Double Triangle design, on average, every 10 tiles will have 9 of those tiles covered by a mining drill. Thus is has a space efficiency of 90%.
