Yes. So even with 40% survival to 3" you could achieve the goal of 100,000 3" BG. Considering the biologist thought the >3" BG was what was in short supply, keep in mind that 1" to 3" BG are not being consumed by BG (but rather are being consumed by LMB up to about 18"). They can only eat so many so fast so the loss of your supplemental BG will only be the amount the <18" LMB were short relative to consuming ad libitum. It is possible that you will get more surviving than they recommended. You may want to talk with them about whether exceeding 100,000 3" BG per annum is something they would be concerned about. All things considered; I would prefer to have too many smaller BG than not enough 3" BG.
