Do I need to add more campden?

Hi,

I made a novice error and have a strange situation.

48 hours ago I added 4.5 crushed campden tablets and poured over 4lbs of crushed raspberries berries.

For every gallon of wine produced, 3.5 lbs of berries are being used.

I'm doing a 7 gallon batch of wine.

If I add an additional 22 lbs of berries, will the campden I added 48 hours ago still kill the wild yeasts in these new berries? Do I have to add more campden, and if so how much?

Well I added an additional 3 tablets and blended everything together...should be fine because I poured boiling water over berries as well.

additional tabs seems right. running standard is 1 camden tab per gallon of must.
