fixed data paths for HCS use; added notes re random re-sampling process; removed word version as they won't match (due to random re-sampling process)

added further data cleaning - slightly adjusts initial plots and results; results based on random re-sample will not now match the paper due to random processes

filtered out -ve HP power values (assumed to be instrument error); corrected file loading data type error, re-built small & larger sample analysis

amendments to descriptive stats. unclear if this is latest version - proportion analysis is incorrect
