Turboflakes Grade
era 10139
Β· captured 2026-10-12T11:13:25.719008
This grade does not affect your rewards or slashing risk.
It measures parachain-backing performance only - useful as a quality signal for nominators, not a financial penalty.
All four signals healthy - no action needed.
Grade
A+
β² excellent
Explain
What this is. Turboflakes grades each para-validator per era. A para-validator is a validator picked by the relay chain each session to verify parachain blocks - assignment rotates so every active validator takes turns.
The 9 bands (best to worst): A+, A, B+, B, C+, C, D+, D, F. The grade is computed from your vote ratio (75%) and bitfield ratio (25%) - see MVR and BAR tiles for the inputs.
Yours: A+ - Top-tier para-validator performance.
Calculated by Turboflakes from on-chain parachain backing data for era 10139.
MVR - Missed Vote Ratio
0.47%
β² excellent
Explain
What this is. When you back a parachain block as a para-validator, you cast one of three votes:
- Explicit - you ran the block yourself and signed off. (316 this era)
- Implicit - you trusted another validator's signed vote. (106 this era)
- Missed - you cast neither. (2 this era - these hurt your grade)
Formula filled with your numbers:
MVR = missed / (missed + implicit + explicit)
= 2 / (2 + 106 + 316)
= 0.47%
Bands:
- < 5% - excellent
- 5β10% - healthy
- 10β20% - slightly elevated
- > 20% - flagged with β glyph by Turboflakes
Network median this era: 0.0%
- yours is
significantly above median - likely a node-side problem.
Calculated by Turboflakes from on-chain parachain backing data for era 10139.
BAR - Bitfield Availability
99.77%
β² healthy
Explain
What this is. Separately from voting, every validator (not just para-validators) signs a small message each block - called a bitfield - declaring which parachain blocks they currently have the data for. This is how the network knows a parachain block is safe to finalise.
Formula filled with your numbers:
BAR = signed / (signed + missed)
= 3482 / (3482 + 8)
= 99.77%
Bands:
- > 99% - healthy
- 95β99% - mild lag, usually transient
- < 95% - node not keeping up with relay-chain block production
Calculated by Turboflakes from relay-chain block data for era 10139.
Para-validator inclusion:
100.0%
- fraction of sessions in this era when you were picked to back parachains.
Random rotation (every ~10 sessions on Polkadot) - informational, not a quality signal.

era 10139
Pattern:
very stable.
MVR rarely moves more than Β±1pp between eras - your node is consistent.
Network rank:
Bottom 30% by MVR in 5/5 eras - your node is below network norm.
Para-validator role:
picked in 5/5 eras
- this is rotation by the relay chain, not a quality signal. Eras where you weren't picked have no MVR/grade.
