seems bed tables are same for new and old generation
here are the measurements done

which narrowed to usage range give

when doing a trendline it is clear that Generation 0 and 1 have same parameter for bed

So actually difference of results between David and Ogremustcrush are on highest temperature and related to measurement way and environement (https://github.com/luc-github/Repetier-Firmware/issues/83)

New table for bedGen 0 & Gen 1 is implemented 0771531

New table for Extruder Gen 0 is also implemented
No new table for Extruder Gen 1

Check https://github.com/luc-github/Repetier-Firmware-0.92/blob/master/bed-extruder-tables.xlsx

Hi Luc I also generated tables for extruder and bed for my 1.0 I did notice one small issue with my 1.0 bed.. I have access to a multichannel temperature probe, so I attached 3 sensors on the table to measure the temperature. Depending on the temperature , there is up to a 7C difference in temperatures over the table during heating, after the temperature is stabilized over 5 mins these equalized out to withing 0.8C

Hi Garry, to update bed table, I relied on David work, check here https://github.com/luc-github/Repetier-Firmware/issues/83
He did a lot of measurement minimizing the environment effect, including stabilization time like you mention.
but if you have additionnal data - feel free to share - everything to make table reliable is welcome
On my side because it is cold here, unlike your 30 degres ;) I can verify low temperatures and check sensor does not generate error in low temperature
