They all looked halfway decent but I could never get a decent speed solution. It varied anywhere from 6 to 10 knots. These were all manual calculations, I never use the button to find it. I took 4 shots. Nevermind that 3 prematurely detonated (not the point of this thread). I missed way behind so he was either much faster or further away than I had ranged him. So I cheated and reloaded. Further ranges showed him almost 700 yards closer. I'm pretty confused. SH 3 always seemed to be much better at periscope ranging. Any mods that work with TMO and RSRDC to fix this?

If you aim for realism, you should be happy with the stadimeter error. Real life skippers had the ordeal of measuring the mast of the sighted ship, and the Length/Height Ratio which helped them call the AOB.
Another thing, is that the TDC feature is nice to keep on as soon as you start a plot. At least you have a projected path, which you may update conveniently. Alas, the TDC wont give you a precise ranging, but if the difference between expected stadimeter range and TDC generated range is off by 100 meters, the solution is valid.
For example you start plotting when the target is 20 kms away. 2 sound bearings and pings get you an estimate course and speed and a first-hand AOB. these you plug-in with a compensation of AOB (say at 19.7 km a ping ranged got him at AOB 13 starboard, so you adjust AOB to 14 starboard and range of 19.5 at the next bearing then you turn on the PK).
Works well if you track with sonar. Radar can be keyed to show range/bearing consistency and correct if necessary (mostly if the target is in deep waters and not facing a puddle or landmass ahead, the solution stays same with minor adjustments at pre-firing point).
By 'keying' the radar, I mean focus on a bearing ahead of the target an most importantly, recognizable on the PPI screen (30 degree bearing increments themselves,not the slices of pizza in-between) and when the target crosses that bearing, you check the A-scope for range and compare it to the TDC generated range, while also checking the generated bearing versus return bearing
