Type IXD2's 23700 NM does not compute!

Not so long ago I posted here Type IXB performance data taken from real commander's KTB entry found on U-boat Archive web-page. Look for some Type IXD2 U-boats KTBs there...maybe similar data were also made. Well, there were not so many Type IXD2 U-boats commissioned - only 29. Have a nice reading...

Speed measures and distances travelled (as for IXB in 1939):

- Cruising speed at 10 knots: 6 days 15 hours 36 minutes = 1596 nm
- Cruising speed at 9 knots: 21 days 14 hours 58 minutes = 4670.7 nm
- Chasing speed at 12 knots: 2 days 5 hours 33 minutes = 642.6 nm
- Chasing speed at 14 knots: 4 hours 35 minutes = 64.25 nm
- Chasing speed at 15 knots: 2 hours 32 minutes = 38.0 nm
- Submerged speed about 2.5 knots: 3 days 1 hour 46 minutes = 64.4 nm
