Richard that is rubbish. The grounds for their condemnation was that they had done something in worship which God had not commanded them. That is what the text says.
The issue is that Jeroboam had done somthing against the explicit command of YHWH. That is what the text says.
And Jeroboam said in his heart, Now shall the kingdom return to the house of David: If this people go up to do sacrifice in the house of the LORD at Jerusalem, then shall the heart of this people turn again unto their lord, even unto Rehoboam king of Judah, and they shall kill me, and go again to Rehoboam king of Judah. Whereupon the king took counsel, and made two calves of gold, and said unto them, It is too much for you to go up to Jerusalem: behold thy gods, O Israel, which brought thee up out of the land of Egypt. And he set the one in Bethel, and the other put he in Dan. And this thing became a sin: for the people went to worship before the one, even unto Dan. And he made an house of high places, and made priests of the lowest of the people, which were not of the sons of Levi. And Jeroboam ordained a feast in the eighth month, on the fifteenth day of the month, like unto the feast that is in Judah, and he offered upon the altar. So did he in Bethel, sacrificing unto the calves that he had made: and he placed in Bethel the priests of the high places which he had made. So he offered upon the altar which he had made in Bethel the fifteenth day of the eighth month, even in the month which he had devised of his own heart; and ordained a feast unto the children of Israel: and he offered upon the altar, and burnt incense.
It is indeed true that Jeroboam invented the date, but the festival was not an innovation. The sin was that he went against what YHWH commanded.
He invented the date of the festival, therefore, it was a human invention and a breach of the RPW. On an NPW basis you have no grounds for condemning him. Besides my comment was directed towards what you were saying in relation to Nadab and Abihu.
To change your position on a subject as serious as this so quickly strikes me as rash. Perhaps you should think for a longer period about matters before stating them publicly (that is not a command, just a suggestion). It is not good to be always changing your mind as it suggests instability.
