I. Horizontal Plane + Time: Graphs

Eight key locations were chosen from within the central area of the site where access to them was easy; two locations representing each of the four vector directions and thus, allowing observations to be made in more detail. The Polarity allocation of each location was guided by the desire to obtain a matching movement linked to its Vector partner, and adjusted so that a unified horizontal plane group movement was achieved where ever possible. The initial choice of the Compass Rose layout - North 'Positive'/South 'Negative' (shown in fig. 2.27[a] below) later required to be reversed to deal with certain anomalies found in Vector Pn in 2022. The East /West polarity remained unaltered and the remaining three vector directions stayed the same (see inset fig. 2.27[b]).

Initially number data was extracted from the 'positions-over-time' in the pre-existing fortnightly plans dating back as far as June 2014. Later, as confidence in the method grew, accurate measurements were made directly in the field. Both approached allowed the approximate distance of a location from its nearby co-ordinate point to be written in number form into Excel spreadsheets so that instantaneous direct plotting of graphs became possible (see fig. 2.28 below).

Fig. 2.28: Eight Locations - movement over 7 months, June'14 to Jan., 2015 

Seven of the locations were of a similar height above sea level, varying from 43.85 m to 44.60 m (a.s.l.); i.e., with a range of only 0.75 m between them. The eighth and lowest location, (Pn4) was at h. 42.70 m a.s.l., and 1.9 m below the highest point. The measurements allowed the 'range of horizontal movement' to be re-examined and the results showed that in the Midsummer period (5th June to 19th July 2014) the range varied from 0.25 m to 2.11 m and in the Mid-Winter period (10th Dec., 2014 to 27th Jan., 2015) the range was 0.41 to 1.79 m.[*]

[*] On 28/12/14 a single data point for Pn4 was recorded as 7.00 m (!); this appeared to be wildly astray of all the remaining data and so was omitted in order to avoid it giving undue weight in analysis. It is marked by a blank red cell on the appropriate spreadsheet (which should be downloadable in the appendix). Reference to later data for Pn4 at this location on the 28th December, 2015 and again in 2016 gave readings of 1.15 m and 1.03 m respectively (see Excel Spreadsheet data).

The data showed that all were broadly similar in total range but very little variation in each of the individual locations was displayed. The two locations where the biggest swings were recorded, had a similar large range in both summer and winter. However, with no clear image of the overall waveform at this stage, it was difficult to say why there appeared to be such a significant difference in the range of movement between all the locations within the group and how these individual differences might relate to the 'Moving Wave' hypothesis.

Although these fortnightly intervals for observations made in 2014 were relatively sparse, nevertheless some conclusions could be drawn from them. When the Summer to Winter totals of the 'Eight Locations' data were combined on a spreadsheet and then displayed as a stacked graph, they appeared to show a movement over time from 'Negative' to 'Positive'; i.e., from a Westerly (-ve) point in the Summer, shifting to an Easterly (+ve) point in the Winter Period (see fig. 2.28 above). This trend had not been obvious from the drawn plans, and reopened the possibility that perhaps a 'magnetic-field' type of steady drift might be occurring.

To test this possibility fortnightly observations continued to be made over the following six months – through to the Autumn of 2015. They produced results showing that the drift did not continue but instead appeared to reverse (see the stacked graph for the Eight Locations shown in Fig. 2.29 below). Thus, the theory of a 'Magnetic-field' type of movement was yet again found to be unsupported. Instead, the evidence seemed to indicate the existence of an 'Annual Cycle'.

The concept of an Annual Cycle was then tested by combining the earlier 'fortnightly' surveys that had been drawn directly in the field (2014/15) to produce a single plan of the site. This depicted the six months of Winter in the colour Blue (Nov.'14 to Feb.'15) and six months of Summer in Orange (May to Aug.'15). The combined plan (shown in fig. 2.30 below) appeared to confirm that the movement being recorded was indeed that of an annual cycle. Further, closer examination showed the path of Dn3 to be a twisted S-shape running from NW to SE, combining both 'positive' & 'negative' movements along its length; apparently dependant on the height above bedrock at which the observation was made. This appeared to be the same vertical plane movement in opposite directions already seen on Dn3 between the Ground Floor and 1st Floor within the house. This proved to be a Pivotal moment in the investigation.
