Slippage Comparison of MQL5 Signal

 
When following MQL5 signal, should I open an account under the same server as the signal provider?

Based on the attached picture, it looks weird that the server XMGlobal-MT5 2 (same as signal provider server) has a much higher slippage of 5.46.

Weird or not that is the case, the signal provider's server is not always the best choice.
