SUBSIM Radio Room Forums - View Single Post - Auto TDC consistently misses (torps arrive late always)

Just tested, both with and without duds enabled and can confirm this.

Shooting at targets 1112 and 2386 yards away using high and low speed torpedos. Stationary targets directly 0 degree bearing from the bow so no error introduced by torpedo turning etc. Ie totally straight line shots.

Formula used:

(Range in yards / 2025) * 3600 then dividing that figure by number of seconds to take to hit target.

Raw results:

Range 1112 yards, TDC claims 40 second travel time, it takes 56
Speed = 35.30kts

Range 1112 yards, TDC claims 40 seconds travel time, it takes 55.5
Speed = 35.35kts

Range 2386 yards, TDC claims 1min 30 seconds travel time, it takes 1min 57
Speed = 36.25kts

Range 2386 yards, TDC claims 1min 30 seconds travel time, it takes 1min 58 seconds
Speed = 36.30kts

Test average:- 35.8kts

High speed torpedos

Range 2382 yards, TDC claims 2 min 13 second travel, it takes 2min 13 seconds. TWICE
Speed = 31.8kts

Some variation in the numbers there but important to note the TDC time estime and actual are identical for LOW speed torpedos. With averaging etc this is probably 32kts

For the HIGH speed there seems to be more variation so would need more tests, the further the distance the better to reduce error. However it seems to be doing about 36kts. No higher. Definately not 46.

Looks like you've found out WHY these torps are missing. Hopefully its a simple 1 hex edit mod to fix. Could be fade but if it was id expect them to randomise speed somewhere and on all torps to keep it err "interesting".

Note this was on a "taking forever" game load attempt for me if it makes any difference.
