Turboflakes Grade
era 9202
· captured 2026-02-20T00:13:17.200758
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+
▲ 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 9202.
MVR — Missed Vote Ratio
1.71%
▲ 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. (267 this era)
- Implicit — you trusted another validator's signed vote. (20 this era)
- Missed — you cast neither. (5 this era — these hurt your grade)
Formula filled with your numbers:
MVR = missed / (missed + implicit + explicit)
= 5 / (5 + 20 + 267)
= 1.71%
Bands:
- < 5% — excellent
- 5–10% — healthy
- 10–20% — slightly elevated
- > 20% — flagged with ✗ glyph by Turboflakes
Network median this era: 0.11%
— yours is
significantly above median — likely a node-side problem.
Calculated by Turboflakes from on-chain parachain backing data for era 9202.
BAR — Bitfield Availability
99.74%
▲ 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)
= 2338 / (2338 + 6)
= 99.74%
Bands:
- > 99% — healthy
- 95–99% — mild lag, usually transient
- < 95% — node not keeping up with relay-chain block production
Calculated by Turboflakes from relay-chain block data for era 9202.
Para-validator inclusion:
66.7%
— 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 9175
■ para-validator era
era 9202
Pattern:
some variance.
MVR moves by a couple of percentage points between eras — normal range.
Last 7 eras:
steady — no significant change in average MVR.
Network rank:
Bottom 30% by MVR in 15/27 eras — your node is below network norm.
Para-validator role:
picked in 28/28 eras
— this is rotation by the relay chain, not a quality signal. Eras where you weren't picked have no MVR/grade.
