Feedback for Affinity write-up

I am writing up my affinity diagramming results, starting with a category I am confident will remain (I am using this write-up to make sure I didn't miss anything). Can you guys give me some feedback on a sample of this, to make sure my form is correct? The titles are subject to change. 

        4.3.5 Appropriate Cache Use

The use of caches for citizen science is core to this research, and when caches would work was a topic of conversation in every discussion. There was agreement of the potential caches provided for more systematic data collection. Different factors were discussed that would influence whether a project warranted physical caches, physical caches, virtual caches, or a combination of the two. The remainder of this section covers those factors.

Number of Visits

The core element to consider when choosing the cache type is the number of visits needed to a site. Our participants agreed that anytime a site needs to be visited again, a physical object would make the site easier to find [P1-9]. Even if repeat visits were not needed, marking a cache would allow the site to be returned to if there were interesting/possibly incorrect parts of the data [P4]. This is in conflict with possible impact from caches [see Impact in 4.3.5]. Participants mentioned using physical objects such as rock cairns [P6&7], rebar [P5] and marking tape [P1] in previous projects. The choice of object depended what was easy to carry or what was on site as well as the time between visits affecting the site [see Destruction of caches in 4.3.5].
