Change to scout cav conversion time?

The most recent update changed how conversions work for the scout cav and Eagle lines.

"Scout units [Scout Cavalry & Eagle Warriors]: No longer have extra conversion resistance levels, minimum conversion time increased from 4 ▶ 8."

Does anyone know exactly how this has affected conversion times for these units?

My broad understanding is that it's not massively changed average conversion time, but has made conversion times a bit more consistent for these units. But I haven't seen any more in-depth analysis on this.
