It's not possibile 172.785 brt total for 199 ships, it's too small. In this moment I've in my list 175 ships for 325.111 BRT
Byelorussian historian A.Taras  and Russian historian K. Strelbitsky  give the following number - Soviet submarines sank by torpedos and artillery fire 146 ships and warships [172.785 brt] during WWII + 46 ships/warships exploded on submarine's mines = 192 ships.
Professor Platonov  gives the following number for submarines [my summing up of the data from his tables per year and navy, per torpedos/artillry/mines] - North Navy [37 ships - 95565 brt + 18 warships], Baltic Sea Navy [48 ships - 143265 brt + 5 warships], Black Sea Navy [35 ships - 56181 brt + 11 warships], Pacific Navy [4 ships - ~3900 brt]. So Soviet submarines sank 124 civil ships [298911 brt] and 34 warships during WWII = 158 ships. In reality this amount could be more significant as Platonov counted and desrcibed victories according to confirmed foreign sources only and doubt victories are not taken into consideration.
