Yes, I've considered doing that, both for calculational investigations like the one you're describing and also for historical data which was usually given in minutes and seconds. Probably an alternate "expert" entry page would be nice.
In the short term, there is a trick you can use: when you clear a lunar using my web tool, you will notice that there is a very long URL for the page where the clearing is displayed. This URL contains all of the data that has been entered on the input page, and it can be edited directly. If you go to the end of the URL, you will find something like "&LunarDeg=47&LunarMin=23.1" indicating that the entered lunar distance was 47 degrees 23.1 minutes (input items in URLs are separated by ampersands, the item names are mostly obvious). Although the entry page only allows you to enter 23.1 to one decimal place for the "lunar minutes", you can edit the URL by hand and add a half dozen more digits if you have an inclination to do so. So you could change the URL to include "&LunarDeg=47&LunarMin=23.12345" instead of the original entry and then re-load the page. The calculation engine will use the adjusted value. Also note that you can create your own customized data entry page as long as it feeds the URL to the calculating page properly formatted. For example, there is a Spanish web site which I discovered by chance that sends requests to my web tool from a Spanish-language version of the input page (it only makes one mistake in the URL).
Incidentally, the web tools are written in Basic. :-)
