Is this normal? Big drop on bench

[clemsonmike]

I was benching 205x5x3 albeit not using correct form. I am currently squatting 255x5x3 and deadlift 285x5x1. I’m now taking bench press seriously and focusing on form and technique according to Ripp and SS method; however my bench is now 165x5x3. Is this normal and to be expected?

Thank you so much!
Mike
