1.In regard to the group formation process, I happen to have some advice that you might want to take a squint at.
Above is a sentence I wrote in my letter to the club chairman. In one of our after-class meetings, he made us team up for a group project. But as it turned out, the whole process didn't go as smoothly as he thought it would be. So I wrote a letter to propose some ideas that might help to improve it.
However, I am not quite sure about the expression in bold. Does it sound natural to you? If not, I'd like to ask if any of the following options is acceptable in this context.
2.In regard to the process of getting into groups, ...
3.In regard to the process of putting groups together, ...
4.In regard to the process of assembling into groups, ...
5.In regard to the assembling of groups, ...
If none of the above seems right to you, please feel free to provide your own options.
