My opinions:
Too much detail? -Absolutely not, the profile you have created is good, and obviously well-researched.
Can you have too many sources? Absolutely yes - but the profile you have linked is not an example of that problem. What constitutes too many sources is not simply a question of quantity but also of quality and utility.
Generally I avoid using more than one footnote for a single fact. (I have seen gedcom with 13+ citations - for one fact!)
The main exceptions to one fact-one source are a) cases where two primary records exist, for example a death registered where the death occured and also registered where the person resided, and b) one citation and one explanatory footnote.
When sources agree there is no real need to cite each source - at most an annotation to the citation such as:
Hale, 2008. [Madan and also others support this fact]
When sources are inconsistent or disagree either i) all versions should be presented in the bio as a disputed fact (each sourced independently), and/or ii) an annotation and/or explanatory footnote should be used to explain why the version of a fact in the bio was chosen over other versions; for example:
Orcutt, 1886. [Burritt instead gives the date as 1650; this is believed to be a typo as Burrit relied heavily on Orcutt and elsewhere explains when the two works diverge,]
There can also easily be too many sources when they are all of unknown/questionable accuracy - citing 5 or 10 ancestral files or member trees is way too many.
