Once upon a time in a former life I had an industrial customer that used 10BASE5 and it ran all around their factory. One of the many jobs I did for these folks was installing vampire taps and AUI drop cables.
As you mention the optimal placing of a tap should be on these marks, or as close to as possible. Unfortunately the reality was that where these cables ran and where the taps needed to be fitted and where the dots actually existed never really aligned well, especially in high up confined crawl spaces. We soon discovered that 10BASE5 is pretty forgiving even if you install a tap in the least optimal positions, e.g. dead centre between the dots.
Previous installers even managed to install two to three taps more or less next to each other and there were no complaints about performance degradation.

- ggm 5y agoWe used to joke that fixing campus CATV cable meant removing the end-tap over night to let the surplus electricity drip out. The thing is, during this time 2mbit telco cabling sometimes was a gas filled conduit, and your comms data frame included pipes with brass taps, and small buckets: they got leaks, and you had to drain water sometimes.
