Nuance testing: My findings on synonym usage

I’ve been experimenting with synonym nuances lately. For example, when discussing the history of 製薬 companies, I initially used the wrong 'fast.' After switching to 早い for 'early' history versus speed, my comprehension improved. I also noticed how 通話 is strictly for the call duration itself in logs. Does anyone have a systematic way to test these subtle shifts in meaning before they cause confusion?
