I have had the same issue with the BB Kits. If you calculate the OG given the ingredients it is always lower than they state on the instructions.

Use these values in your calculations:
LME is 1.036 per pound per gallon use 36 points per gallon
DME/Sugar is 1.040 per pound per gallon use 40
Specialty Grain is 1.025 per pound per gallon use 25

To Calculate for the BB Imperial Pal Ale:
6.6 lb LME
1 lb of DME
1 lb of Sugar
Sp. Grains 1.75 lbs

LME 6.6 * 36 = 237.6
DME 1 * 40 = 40
Sugar 1*40 = 40
Grain 1.75 *25 = 43.75
-------------------------
Total = 361.35

Then Just divide by the final # of gallons which would be 5.

361.35 / 5 gallons = 72.27 or 1.072 OG

The Kit says it should be 1.081-1.085. The math says you should get 1.072. You got 1.070. I'd say you did good.

I hit the calculated value every time with the BB kits.

It is the supplier that is responsible for you reaching the stated OG, not you. Your supplier appears to be cutting you short. I personally find it abhorent that suppliers consistantly cut their patrons short on recipes. One should, in my opinion, contact the supplier and clue them in on the shortfall. After all in an extract brew, the OG is the supplier's responsibility, not yours.
I agree....NB kits always hit the OG...other kits...not so much!

I've been having the same problems with BB kits. Gonna try a new brand (either NB or Midwest) and take note of those calculations!
