Your point is that chart position doesn’t matter for This Missy album because three albums on the chart sold a lot, and absent those high selling albums, she would have debuted in the top 5.
But even without those albums, she only gets bumped up to 7. So it doesn’t prove your point.
Initially, you said 10 was disappointing. I explained to you why Missy was #10 and now you're saying if you removed the Top 3, she's be higher. That was my point. The chart positions are irrelevant because literally any sales figure could score you a higher or lower chart position based on individual sales AND the competition. This is why 129K in 1997 was enough to get her a #3, while 131K (although more than 129K) only got her a #10 in 1999. 9 other albums did more than she did that week.
