From: miller@math.psu.edu (Donald S Miller) Description: SFB: How to calculate BPVs (long!) (was: SFB construction?) Here's a system I use to calculate BPV which gives results fairly close to their (Task Force Games) BPV's: 1. Add together the box value for each box on the SSD (values found below). 2. Apply the following increases: +50% if the ship is a 1X design, +30% if the ship has a cloaking device, +10% for stealth (and others that I forget right now, sorry!) 3. Divide the result by 2.5. This is the Economic BPV of the ship. Box values (some of these are ripped from SFB Commander's edition annexes): Hull (F,A) 1 Hull (C) 1.2 Cargo 1 Tran 1 Trac 1 Trac-Mech Link 2 Shuttle 1 for each box, 1 for each bay, 2 for each admin shuttle Fighter Box +1 more (but don't pay the 2 admin shuttle cost) Launch Tube +1 more Lab 2 Probe 2 Repair 3 Hold (2X) 4 Armor 1.5 Bridge 3 AuxCon 3 Emer 3 Flag 3 Scty (extra) 2 Btty (1 pt.) 1 Btty (5 pt.) 5 Warp (L,R) 4 (5 for orion) Warp (C) 5 (6 for orion) Impulse 3 (4 for orion) PF Warp Pack 3 APR 2 AWR 3 Shields 1/6 PA Panel 4 Sensor "6" 2 Sensor "5"-"1" 1 Sensor "0" 0 (no more than 1 per ship) Scanner "0" 2 Scanner "1"-"8" 1 Scanner "9" 0 (no more than 1 per ship) DamCon equal to number in box, no more than one "0" per ship ExcDam 2 for every box beyond: hull/3+1 (round down) Ph-1 2 * Ph-2 1.5 * Ph-3 1 * Ph-4 4 * Ph-G 3 * Photon 5 * Disr 4 * Fusion 2 * Hellbore 8 * PPD 20 * Pl-D 5 * Pl-F 4 * (-1 for each box beyond the first for ISC) Pl-L 7 * (without 1X tech, this a Pl-G that cannot upgrade to Pl-S) Pl-G 10 * Pl-S 15 * Pl-M 17.5 * Pl-R 20 * Drone-A 4 Drone-B 5 Drone-C 5 Drone-G 6 ADD 2 ?

There are probably a lot of systems I have forgotten (I am doing this by memory believe it or not). If there is any interest I can get my real list from home and post it (that list is much longer and includes a FASA Star Trek to SFB conversion). This is roughly based on the old (S3.3) in Commander's Edition but with a constant divisor. This system has some obvious problems, but it does give BPV's usually within 20% of their reported TFG value (again, with certain exceptions). Donald Miller
