LT Spice Problem

[CapSteel]

I'm running a frequency sweep of a simple RLC circuit using LT Spice. At a frequency of 100Hz the phase shift of the current should be about 51.8 degrees based on hand calculation. However, the LT Spice simulation shows 123 degrees. I've double and tripled checked my calculation, but cannot get the LT Spice simulation to match. Does anyone have any idea?

Easy peasy: The current through V1 as indicated by LTSPICE is negative with respect to the voltage (it "flows" from + to -, observe the arrow when attaching the current probe in the schematic. This implies a phase reversal by 180 °.
Do the math: 180 ° - 123 ° = 57 °. This is in accordance with the result from e.g. this calculator using the above component values. Your manual calculation is off by only 5 °, possibly due to rounding errors?

Thanks a lot for the help!!!! It all makes sense now.
