FutureClusterMatch chi2 is unstable
The Brunel test brunel-upgrade-test-protos keeps failing on lhcb-run3-cleanup as a chi2 is varying randomly in its 7th digit. Here:
FutureClusterMatchSUCCESS Number of counters : 5
| Counter | # | sum | mean/eff^* | rms/err^* | min | max |
| "#above threshold" | 10 | 344202 | 34420. | 18422. | 9679.0 | 59794. |
| "#chi2" | 111342 |5.171904e+07 | 464.51 | 288.26 | 0.00039632 | 1000.0 |
| "#good tracks" | 10 | 1740 | 174.00 | 60.080 | 86.000 | 253.00 |
| "#links in table" | 10 | 111342 | 11134. | 6556.8 | 2189.0 | 21141. |
| "#total calos" | 10 | 2414 | 241.40 | 62.049 | 138.00 | 334.00 |
but sometimes that 5.171904e+07 is a 5.171906e+07 or 5.171903e+07. I'll wait for the next lhcb-head build to see if this is a L0-related issue (so lhcbrun3-cleanup) or a general one. So no action now.
