One thing I have noticed was that going from BBLv 9 to 10 was very difficult (I must have fused 100+ units to achieve) Once I hit 10, the SBB levels are going exponentially faster (I'm at BBLv 15 after fusing ~30 more units) It seems the difficulty resets once you hit 10, and I assume it will ramp up again once I get close to BBLv 20.
