Note that the equivalent width (EW) parameter can have a huge impact as it varies the time of concentration. However, this is only an issue if you are using a time of concentration method that uses the EW parameter. For example, if you are using the SCS time of concentration method, then the EW parameter has no impact since it is not used in the computations of the time of concentration.

Hope that this helps. Let me know if you still need additional assistance.
