Passiflora: I do understand,believe me, in wanting only a quality chart. I think Jenner's meets this stricter criteria too.
Actually, your post reminded me of the late astrologer in Australia very popular man who passed a few years ago and is greatly missed by most astrologers.
He too could hit the ceiling IF a time of birth was the least bit questioned.
His name was Ed Tamplin and he had a wonderful Blog for Mundane Astrology which was extremely popular. Perhaps 2 years or less before he passed away, as we were FB (friends) I did a chart for HRC for her run for the Presidency. I used the popular tob then, which I must have gotten from astro.com.....but I wasn't "1,000% positive" it was correct and said so.
Ed had a sh-- fit over it. I don't think we talked since. As it turned out, the tob was eventually rated DD -
So I can understand how some astrologers are....and I personally am not that way, BUT, I do understand their higher standards too and think no less of them for it.
He stopped posting his popular blog in October 2019 - (and his last on FB) and died of brain cancer only weeks thereafter . Rest in Peace ED -

I still have people messaging me asking for his Blog, which is no longer available, except perhaps from a site like Wayback Machine?
