I took slash's base HP (3376) and the amount he said each house healed. I then divided the amount healed by the base max Hp. The answer you get, you multiply by 100 to get a percentage.

eg:-270hp divided by 3376 = .07997
you multiply this by 100 to get a % = 7.997%

He said it healed this much over 2 seconds so I divided 8% by 2, to find how much it healed per second. Presto.

Tell me if this is the right way to do it or if I went wrong somewhere.

@Lvra - Ur figures looks right to me!
