Hi Shourya - thank you for sharing your experience here!

The short answer here is suitable values for lambda weighting parameters tend to be extremely dependent on the PDE, application, and point sampling strategy. So, making a general purpose recommendation or default here unfortunately isn't really possible. However, this is definitely something we can make more clear in our theory document, so I've implemented those changes in #252 to help future users!

Thanks!
