Is this PM boil correct??

This is the original :

10 lbs Pale Malt (2 Row) US (2.0 SRM) Grain 90.91 %
1 lbs Caramel/Crystal Malt - 60L (60.0 SRM) Grain 9.09 %
1.00 oz Northern Brewer [8.00 %] (60 min) Hops 23.9 IBU
0.50 oz Northern Brewer [8.00 %] (30 min) Hops 9.2 IBU
0.50 oz Northern Brewer [8.00 %] (0 min) (Aroma HHops -
1.00 items Whirlfloc Tablet (Boil 15.0 min) Misc
1 Pkgs San Francisco Lager (White Labs #WLP810) [Yeast-Lager

My grain bill called for :
5LB's of pale malt two row
1 lbs of caramel/crystal 60L
Now beer calculus says 2lb of xtra dry is sufficient I was going to throw in 3lbs.

Should I go two pounds or three??

This is an Anchor steam clone by the way.
