Thanks Brian, I used your data in the end but for anyone else using this the following may be useful.
My Chroma LRGB filters are 27040/27041/27042/27043 respectively and Batch numbers 371196/370234/370232/370883 respectively - purchased 14/10/2020.
I downloaded the data for the 2704x filters from Chroma and graphed it. The graph looked fine however when compared to the certificate that came with the filters for my batch the graph was slightly different.
However, when compared to Brian's data above the graphs matched my certificate very closely - I didn't check every value but visually the graphs were identical.
It's possible the slight differences between sources wouldn't make any difference in practice, I don't know, but if you have original documentation that came with the filters its probably worth checking the data matches.
