[FASTBOAT TOUGH]

Don,
I think I follow that older tanks etc. will have the negative factor applied while newer ones will have the positive factor applied if we keep this in the KISS frame of mind for guys like me. What I'll simply do is provide the info as to type (If any applied to the tank or other.) without comment and let you do the math. This way there'll be a record of it to avoid or minimise any further discussion of a piece of equipment down the road. In another words I'll try to make the package more complete as I started doing to include ATGW self protection equipment last year.

Regards,
Pat
