you just decided to post them even though it would be helpful to someone like me but to me it seemed like you didn't have anything to say regarding op.
Those links are definitely useful. There's nothing wrong with not commenting on the OP post either. Not like we have to do that just to comment on the thread to begin with. Is there a reason why you comment on this?
Speaking of useful links, IIRC mempool.space allows you to check transaction weight easily. CMIIW.
